Without that patch the search path for `install-sh` will become $HOME

The generic event structure xcb_ge_event_t has the full_sequence field

This fixes a deadlock which was seen in-the-wild with wine.
It could happen that two threads tried to read from the socket at the same time
and one of the thread got stuck inside of poll()/select().
The fix works by making sure that the writing thread doesn't steal the reading
thread's reply.

On FreeBSD MSG_WAITALL on a non-blocking socket fails immediately if less bytes
than were asked for are available. This is different than the behavior on linux
where as many bytes as are available are returned in this case. Other OS
apparently follow the FreeBSD behavior.
_xcb_in_read() is used to fill xcb's read buffer, thus this function will call
recv() with a big length argument (xcb's read buffer is by default 16 KiB
large). That many bytes are highly unlikely to be available in the kernel
buffer.
This means that _xcb_in_read() always failed on FreeBSD. Since the socket was
still signaled as readable by poll(), this bug even resulted in a busy loop.
The same issue is present in read_block(), but here it is slightly different.
read_block() is called when we read the first few bytes of an event or a reply,
so that we already know its length. This means that we should be able to use
MSG_WAITALL here, because we know how many bytes there have to be.
However, that function could busy loop, too, when only the first few bytes of
the packet were sent while the rest is stuck somewhere on the way to us. Thus,
MSG_WAITALL should be removed here, too.
Thanks to Christoph Egger from Debian for noticing the problem, doing all the
necessary debugging and figuring out what the problem was! This patch is 99%
from debian. Thanks for all the work.

Fix a redefinition problem which shows up when building for _WIN32 and
libXdmcp is installed, so HASXDMAUTH is enabled
It seems this is a special place in xcb as it uses other X11 library headers here
If HASXDMAUTH is defined, include the wrapped windows.h before any header which
includes it unwrapped, to avoid conflicts with types defined in X headers
We need to include config.h and check HASXDMAUTH to avoid an unconditional dependency
on x11proto headers

This reverts commit 0e9246def5.
This change caused build failures because <X11/Xdmcp.h> was never
included under any circumstance. This is because the check for
HASXDMAUTH was moved before the inclusion of config.h (via xcbint.h)
which defined it.

The alternative is to use these in every WIN32 application which uses xcb. Doing
it this way should be safe, as, according to MSDN, "There must be a call to
WSACleanup for each successful call to WSAStartup. Only the final WSACleanup
function call performs the actual cleanup. The preceding calls simply decrement
an internal reference count"
(We should probably also include ws2_32 in Libs.private for libxcb, as anything
which links with libxcb will also need that, but there seems to be some pkg-config
issues to resolve first...)
v2: Check for errors so WSAStartup()/WSACleanup() uses are balanced
v3: Use same indentation style as surrounding code
