* Use evutil_socket_t instead in http server sample and handle 64 bit Windows
* Update http-server.c
* consistently using EV_SOCK_FMT for Windows compatibility
* code review: fix missing symbol strsignal
* Add evutil_strsignal() helper instead of strsignal() macro

Replace evws_send with evws_send_text, and introduce new API -
evws_send_binary, that can be used to send binary frames.
But note, that this commit breaks the ABI compatibility, but it should be OK,
since there was only alpha release with evws_send, and nobody should rely on
this, and I hope nobody does (we decided to go this way to avoid supporting
deprecated API).
This adds few functions to use evhttp-based webserver to handle incoming
WebSockets connections. We've tried to use both libevent and libwebsockets in
our application, but found that we need to have different ports at the same
time to handle standard HTTP and WebSockets traffic. This change can help to
stick only with libevent library.
Implementation was inspired by modified Libevent source code in ipush project
[1].

Also, WebSocket-based chat server was added as a sample.
Since OpenSSL 3.0 there is new OPENSSL_VERSION_MAJOR, but previous
releases does not have it.
So let's use plain old OPENSSL_VERSION_NUMBER to avoid more preprocessor
macros.
* Don't use deprecated functions when building against OpenSSL 3.0.
* Recognise that OpenSSL 3.0 can signal a dirty shutdown as a protocol.
error in addition to the expected IO error produced by OpenSSL 1.1.1
* Update regress_mbedtls.c for compatibility with OpenSSL 3
The C standard gurantees that an unsigned short is at least up to 65535
huge. Enough to store every TCP port. Also the parameter PORT is
overgiven to the `htons()` function which assumes that the parameter is
of type `uint16_t` which unsigned short is on most platforms.
Move the pragma ignoring outside the function to fix the build with gcc.
While here, add equivalent clang pragmas to mute the warning, as well.

The existing error pages are very basic and don't allow for
multi-lingual support or for conformity with other pages in a web site.
The aim of the callback functionality is to allow custom error pages to
be supported for calls to evhttp_send_error() by both calling
applications and Libevent itself.
A backward-incompatible change has been made to the title of error pages
sent by evhttp_send_error(). The original version of the function used
the reason argument as part of the title. That might have unforeseen
side-effects if it contains HTML tags. Therefore the title has been
changed to always use the standard status text.
An example of the error callback can be found in this
[version](https://github.com/libevent/libevent/files/123607/http-server.zip)
of the 'http-server' sample. It will output error pages with very bright
backgrounds, the error code using a very large font size and the reason.
Closes: #323 (cherr-picked from PR)
