Cygwin and MSYS2 are POSIX layers implemented on top of Windows.
Use our POSIX `poll(2)` implementation of our poll abstraction.
For most other components we already have dedicated sources
implementing them in terms of APIs available on Cygwin or
providing non-implementations of components not supported.
This leaves only three components that need Cygwin-specific
implementations:
* uv_uptime: implement using sysinfo
* uv_resident_set_memory: add a placeholder returning UV_ENOSYS
* uv_cpu_info: add a placeholder returning UV_ENOSYS
Update our test suite to account for features not available
due to Cygwin platform limitations or our placeholders.

Introduce two new APIs:
int uv_tcp_init_ex(uv_loop_t*, uv_tcp_t* handle, int flags)
int uv_udp_init_ex(uv_loop_t*, uv_udp_t* handle, int flags)
The lower 8 bits of the flags field are used for the socket domain.
AF_INET, AF_INET6 and AF_UNSPEC are supported. If AF_UNSPEC is specified
the socket is created lazily, just like uv_{tcp,udp}_init.
Some Windows notes:
getsockname fails with WSAEINVAL if the socket is not bound. This could
potentially be improved by detecting the socket family and filling
the sockaddr_in/6 struct manually.
bind returns WSAEFAULT if we try to bind a socket to the wrong family.
Unix returns EINVAL.
