.. to satisfy restricted environment or fuzzers
We are encountering weird issues in the oss-fuzz that the file disappears during
coverage build so I assume some corpus sneaked in, that contains some commands
that end up being executed as part of the coverage run causing it randomly
failing.
The solution I propose is to build fuzzers without ability to call arbitrary
commands on the filesystem (such as `rm -rf /`) as this is not the point the
fuzzers should be testing.
This is controlled by the WITH_EXEC CMake option (enabled by default).

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

For integration with an external mainloop, we need to know how to
replicate libssh's internal poll() calls. We originally through
ssh_get_status() was that API, but it's not really - those flags only
get updated from the *result* of a poll(), where what we really need
is to know how libssh would *start* a poll().

chapter 1- SSH Socket Connections.
I would like to be able to
-Have a ssh_poll_ctx object
-Add a ssh socket over it
-launch the socket connection (using socket functions)
-ssh_poll_ctx_dopoll()
-Wait for the timeout or have the "connected" callback called
