- Update to version 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
- let's hope this version doesn't suffer yet from the regressions
reported in boo#1205778, boo#1205818 (reported against 1.8.2);
we need libX11 thread safe for totem (GNOME 43) :-(

- going back to version 1.7.5 for now to get rid of regressions,
which were introduced by trying to get thread-safe in libX11
itself
- re-introduced U_fix-a-memory-leak-in-XRegisterIMInstantiateCallback.patch
which was not yet in 1.7.5
