scripts/lsan_suppressions.txt: Add more leaks Running "make check" with the clang leak sanitizer reveals some leak reports which are either not our problem or else not a leak which is worth our time to fix. Add some suppressions for these. While we're touching the file, add the usual SPDX header and a comment explaining how to use it.

gitlab: add lsan suppression file to workaround tcmalloc issues The up-coming upgrade to Fedora 37 will bring in libtcmalloc as a dependency of libglusterfs which confuses our fuzz run. Rather than disable the build lets use LSAN's suppression mechanism to prevent the job from failing. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Cc: Daniel P.

ui/spice: add cleanup on shutdown SPICE resources were never freed on shutdown. Add per-subsystem cleanup (display, input, core) and call it from qemu_cleanup(). Move spice-module.c into libui so the qemu_spice ops table links with the rest of the UI code. Add an LSan suppression for a known spice-server leak. Reviewed-by: Daniel P.
