prepare web release 3.1.0 (#1716)

* Fix Multipart consuming payload before header checks

What
--
Split up logic in the constructor into two functions:

- **from_boundary:** build Multipart from boundary and stream
- **from_error:** build Multipart for MultipartError

Also we make the `boundary`, `from_boundary`, `from_error`  methods public within the crate so that we can use them in the extractor.

The extractor is then able to perform header checks and only consume the
payload if the checks pass.

* Add tests

* Add payload consumption test

 ## Unreleased
 
+
+## 3.0.0
+
+* The return type for `ServiceRequest::app_data::<T>()` was changed from returning a `Data<T>` to
+  simply a `T`. To access a `Data<T>` use `ServiceRequest::app_data::<Data<T>>()`.
+
+* Cookie handling has been offloaded to the `cookie` crate:
+  * `USERINFO_ENCODE_SET` is no longer exposed. Percent-encoding is still supported; check docs.
+  * Some types now require lifetime parameters.
+
+* The time crate was updated to `v0.2`, a major breaking change to the time crate, which affects
+  any `actix-web` method previously expecting a time v0.1 input.
+
 * Setting a cookie's SameSite property, explicitly, to `SameSite::None` will now
   result in `SameSite=None` being sent with the response Set-Cookie header.
   To create a cookie without a SameSite attribute, remove any calls setting same_site.
 
 * actix-http support for Actors messages was moved to actix-http crate and is enabled 
   with feature `actors`
+
 * content_length function is removed from actix-http.
   You can set Content-Length by normally setting the response body or calling no_chunking function. 
 
 * `BodySize::Sized64` variant has been removed. `BodySize::Sized` now receives a
   `u64` instead of a `usize`.
 
+* Code that was using `path.<index>` to access a `web::Path<(A, B, C)>`s elements now needs to use
+  destructuring or `.into_inner()`. For example:
+
+  ```rust
+  // Previously:
+  async fn some_route(path: web::Path<(String, String)>) -> String {
+    format!("Hello, {} {}", path.0, path.1)
+  }
+
+  // Now (this also worked before):
+  async fn some_route(path: web::Path<(String, String)>) -> String {
+    let (first_name, last_name) = path.into_inner();
+    format!("Hello, {} {}", first_name, last_name)
+  }
+  // Or (this wasn't previously supported):
+  async fn some_route(web::Path((first_name, last_name)): web::Path<(String, String)>) -> String {
+    format!("Hello, {} {}", first_name, last_name)
+  }
+  ```
+
+* `middleware::NormalizePath` can now also be configured to trim trailing slashes instead of always keeping one.
+  It will need `middleware::normalize::TrailingSlash` when being constructed with `NormalizePath::new(...)`,
+  or for an easier migration you can replace `wrap(middleware::NormalizePath)` with `wrap(middleware::NormalizePath::new(TrailingSlash::MergeOnly))`.
+
+* `HttpServer::maxconn` is renamed to the more expressive `HttpServer::max_connections`.
+
+* `HttpServer::maxconnrate` is renamed to the more expressive `HttpServer::max_connection_rate`.
+
+
 ## 2.0.0
 
 * `HttpServer::start()` renamed to `HttpServer::run()`. It also possible to

-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-//! Helper and convenience macros for Actix-web.
+//! Macros for reducing boilerplate code in Actix Web applications.
 //!
-//! ## Runtime Setup
+//! ## Actix Web Re-exports
+//! Actix Web re-exports a version of this crate in it's entirety so you usually don't have to
+//! specify a dependency on this crate explicitly. Sometimes, however, updates are made to this
+//! crate before the actix-web dependency is updated. Therefore, code examples here will show
+//! explicit imports. Check the latest [actix-web attributes docs] to see which macros
+//! are re-exported.
 //!
-//! - [main](attr.main.html)
-//!
-//! ## Resource Macros:
-//!
-//! - [get](attr.get.html)
-//! - [post](attr.post.html)
-//! - [put](attr.put.html)
-//! - [delete](attr.delete.html)
-//! - [head](attr.head.html)
-//! - [connect](attr.connect.html)
-//! - [options](attr.options.html)
-//! - [trace](attr.trace.html)
-//! - [patch](attr.patch.html)
-//!
-//! ### Attributes:
-//!
-//! - `"path"` - Raw literal string with path for which to register handle. Mandatory.
-//! - `guard="function_name"` - Registers function as guard using `actix_web::guard::fn_guard`
-//! - `wrap="Middleware"` - Registers a resource middleware.
-//!
-//! ### Notes
-//!
-//! Function name can be specified as any expression that is going to be accessible to the generate
-//! code (e.g `my_guard` or `my_module::my_guard`)
-//!
-//! ### Example:
+//! # Runtime Setup
+//! Used for setting up the actix async runtime. See [main] macro docs.
 //!
 //! ```rust
-//! use actix_web::HttpResponse;
-//! use actix_web_codegen::get;
-//!
-//! #[get("/test")]
-//! async fn async_test() -> Result<HttpResponse, actix_web::Error> {
-//!     Ok(HttpResponse::Ok().finish())
+//! #[actix_web_codegen::main] // or `#[actix_web::main]` in Actix Web apps
+//! async fn main() {
+//!     async { println!("Hello world"); }.await
 //! }
 //! ```
+//!
+//! # Single Method Handler
+//! There is a macro to set up a handler for each of the most common HTTP methods that also define
+//! additional guards and route-specific middleware.
+//!
+//! See docs for: [GET], [POST], [PATCH], [PUT], [DELETE], [HEAD], [CONNECT], [OPTIONS], [TRACE]
+//!
+//! ```rust
+//! # use actix_web::HttpResponse;
+//! # use actix_web_codegen::get;
+//! #[get("/test")]
+//! async fn get_handler() -> HttpResponse {
+//!     HttpResponse::Ok().finish()
+//! }
+//! ```
+//!
+//! # Multiple Method Handlers
+//! Similar to the single method handler macro but takes one or more arguments for the HTTP methods
+//! it should respond to. See [route] macro docs.
+//!
+//! ```rust
+//! # use actix_web::HttpResponse;
+//! # use actix_web_codegen::route;
+//! #[route("/test", method="GET", method="HEAD")]
+//! async fn get_and_head_handler() -> HttpResponse {
+//!     HttpResponse::Ok().finish()
+//! }
+//! ```
