Fix potential memory leak of two pointers (xwayland and client)
This backports four patches from weston to solve a memory leak problem
These four patches are:
https://gitlab.freedesktop.org/wayland/weston/-/commit/5a6604a7a2e52e5cd84c1f53724b3f7c325b5dff.patch
https://gitlab.freedesktop.org/wayland/weston/-/commit/f53c05d3c2c19c139c52e9bd621c2654dd3dac69.patch
https://gitlab.freedesktop.org/wayland/weston/-/commit/e2583ca0844bd7a8ce4fc94da9ad67edf49ffd45.patch
https://gitlab.freedesktop.org/wayland/weston/-/commit/8740037a93c7c4400cc381ecf3009d1e4014be07.patch
The following is the valgrind log:
160 bytes in 1 blocks are definitely lost in loss record 39 of 66
at 0x484B64C: calloc (in /usr/lib/valgrind/vgpreload_memcheck-arm64-linux.so)
by 0x4A73C87: ??? (in /usr/lib/libweston-desktop-8.so.0.0.0)
by 0x4A7184F: weston_desktop_create (in /usr/lib/libweston-desktop-8.so.0.0.0)
by 0x487096B: ivi_desktop_init (in /usr/lib/agl-compositor/libexec_compositor.so.0.0.0)
by 0x486F5E7: wet_main (in /usr/lib/agl-compositor/libexec_compositor.so.0.0.0)
by 0x48B010F: (below main) (in /lib/libc-2.31.so)
In agl-compositor/src/composiotr.c
"ivi->desktop->compositor->xwayland" is zalloced by
wet_main()->ivi_desktop_init()->weston_desktop_create()->weston_desktop_xwayland_init()
"ivi->desktop->compositor->xwayland->client" is zalloced by
wet_main()->ivi_desktop_init()->weston_desktop_create()->weston_desktop_xwayland_init()->weston_desktop_client_create()
"ivi->desktop->compositor->xwayland" and
"ivi->desktop->compositor->xwayland->client"
The memory pointed to has not been released
Now, I want to free the memory pointed by the two pointers.
What can do this is the function of weston_desktop_xwayland_fini() in
0003-libweston-desktop-add-weston_desktop_xwayland_fini.patch
And the submission of this patch depends on the first three patches,
so I submitted these four patches.
