includes all of the relevant headers for Windows and UNIX
in one convenient place. If virsocketaddr.h is already
included, then there's no need for virsocket.h

This imports a simpler version of GNULIB's getpass() function
impl for Windows. Note that GNULIB's impl was buggy as it
returned a static string on UNIX, and a heap allocated string
on Windows. This new impl always heap allocates.

The GNULIB termios module ensures termios.h exists (but
is none the less empty) when building for Windows. We
already exclude usage of the functions that would exist
in a real termios.h, so having an empty termios.h is
not especially useful.

It is simpler to just put all use of termios.h related
functions behind a "#ifndef WIN32" conditional.

Windows sockets take a SOCKET HANDLE object instead of a
file descriptor. Wrap them in the same way that gnulib
does so that they use C runtime file descriptors.

While we could in theory use GSocket, it is hard to get
the exact same semantics libvirt has for its current
socket usage. Wrapping the Winsock2 APIs is thus the
easiest approach in the short term.

In changing the socke wrappers we need to re-implement
the nonblocking function too, since the GNULIB impl
expects to be used with the GNULIB sockets wrappers.
