This commit uses the Gnulib 'lock' module to implement a mutex on
the global list of handles which is stored by the library.
Note that Gnulib nicely avoids explicitly linking with -lpthread
unless the application program itself links to -lpthread. Locks
are only enabled in multithreaded applications.

This allows you to save the errno from a previous call and
pass it to reply_with_perror.
For example, original code:
r = some_system_call ();
err = errno;
do_cleanup ();
errno = err;
if (r == -1) {
reply_with_perror ("failed");
return -1;
}
can in future be changed to:
r = some_system_call ();
err = errno;
do_cleanup ();
if (r == -1) {
reply_with_perror_errno (err, "failed");
return -1;
}
This just ensures that we accurately report errors, even if our
error path code doesn't set errno. We won't end up with a bogus
errno left over from a previous call.
This test script allows you to test limited features of the
Windows daemon by running it on a standard Fedora host using
Wine.
Read contrib/README and contrib/guestfsd-in-wine.sh in detail
before using.
Instead of doing a recursive call into the src/ directory to build
the object files, hard link the source files into the daemon
directory and build them separately.

Thanks to Jim Meyering for noticing a typo in the original version.
At the time of writing Gnulib didn't support Win32 for its
fsusage API. Therefore this patch uses GetDiskFreeSpaceEx
if it's available (on Windows) otherwise falls back to using
Gnulib fsusage.
Instead of checking for futimens support and falling back
(incorrectly in one case) to using futimes, use gnulib's
module.
However the gnulib module does not yet support Win32, so
this change is only really useful on platforms like RHEL 5.
