Log Message:
libX11: update to 1.8.1.

1.8.1

This release fixes the --enable-thread-safety-constructor option to the
configure script to work as intended.  In the previous release, the changes
for this option may not have been enabled when the option was not specified
or when the --enable option was specified.

While we have enabled it by default, believing that doing so will reduce
the number of bugs users encounter running libX11 clients, in some cases
it may expose bugs in which clients had previously gotten away with calling
libX11 functions while a libX11 lock is already held, and thus now deadlock,
as discussed in https://gitlab.freedesktop.org/xorg/lib/libx11/-/issues/157 .

      configure.ac: Fix --enable-thread-safety-constructor
      libX11 1.8.1

1.8

The highlight of this release is that we now try to initialize thread
safety ourselves, rather than hope the application does it. This should
resolve a number of long-standing bugs with the libxcb integration,
since the socket handoff mechanism essentially has to be thread-safe.
But regressions are always possible, so please report any issues
introduced by this release.
