For allowing a more ergonomic use and better integration on the
ecosystem, this adds the `std::error::Error` `impl` for our custom
errors.
We intent to drop this hand made code once `derive_more` finishes the
addition of the Error derive support[1]. Until that is available, we
need to live with that.

* Moved actix-http for actix from actix crate
* remove resolver feature
* renamed actix feature to actor
* fixed doc attr for actors, add documentation
* Enforce safety of `downcast_ref` at compile time.
The safety of `downcast_ref` requires that `__private_get_type_id__` not
be overriden by callers, since the returned `TypeId` is used to check if
the cast is safe. However, all trait methods in Rust are public, so
users can override `__private_get_type_id__` despite it being
`#[doc(hidden)]`.
This commit makes `__private_get_type_id__` return a type with a private
constructor, ensuring that the only possible implementation is the
default implementation. A more detailed explanation is provided in the
comments added to the file.
Note that the standard library was affected by this type of issue with
the `Error::type_id` function: see https://blog.rust-lang.org/2019/05/14/Rust-1.34.2.html#whats-in-1.34.2-stable

* Let ResponseError render w/ 'text/plain; charset=utf-8' header (#1118)
Trait ResponseError originally render Error messages with header
`text/plain` , which causes browsers (i.e. Firefox 70.0) with
Non-English locale unable to render UTF-8 responses with non-English
characters correctly. i.e. emoji.
This fix solved this problem by specifying the charset of `text/plain`
as utf-8, which is the default charset in rust.
Before actix-web consider to support other charsets, this hotfix is
enough.
Test case:
fn test() -> Result<String, actix_web::Error> {
Err(actix_web::error::ErrorForbidden("ðtest"))
}
