This commit adds an `agent_socket` field to the session options
and connects the config parser to that option.
`SSH_OPTIONS_IDENTITY_AGENT` is added to allow applications to
set this option for themselves.
agent.c is updated to take the `agent_socket` value in preference
to the `SSH_AUTH_SOCK` environment variable.

Windows has supported unix domain sockets for a couple of years
now; see this article for more information about that:
<https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/>
This commit allows libssh to consider using agent authentication
on Windows systems.
It is mostly removing `#ifndef _WIN32` that prevented the unix
domain socket code from being compiled in, and adjusting the use
of `read(2)` and `write(2)` to `recv(2)` and `send(2)`, as the former
functions are not compatible with sockets on Windows systems.
For mingw systems, afunix.h isn't available so we use the
technique as was used to resolve building with mingw as used
by the curl project in: https://github.com/curl/curl/pull/5170

According to the documentation the return value is the number of
processed bytes, so the returned value is never negative. We should not
use ssize_t in public headers as it isn't available on Windows! We only
have it defined in priv.h!

The current CMakeLists.txt already provides the detection of this library for BSD/SOLARIS/OSX, so CYGWIN can be easily added there for support.

Contaminated errno can happen before strtoul call, thereofore
cleaning it before the call.
The errno is not used for checking later in code if fail happens,
therefore cleaning it right after error.
