util: Limit size of wl_map
Since server IDs are basically indistinguishable from really big client
IDs at many points in the source, it's theoretically possible to overflow
a map and either overflow server IDs into the client ID space, or grow
client IDs into the server ID space. This would currently take a massive
amount of RAM, but the definition of massive changes yearly.
Prevent this by placing a ridiculous but arbitrary upper bound on the
number of items we can put in a map: 0xF00000, somewhere over 15 million.
This should satisfy pathological clients without restriction, but stays
well clear of the 0xFF000000 transition point between server and client
IDs. It will still take an improbable amount of RAM to hit this, and a
client could still exhaust all RAM in this way, but our goal is to prevent
overflow and undefined behaviour.

shm: Close file descriptors not needed
Commit
5a981ee8 implemented a fallback path for platforms which do not
support mremap() such as FreeBSD.
To do so, the file descriptor for the mmap() is not closed immediately
but instead kept as long as the pool exists.
That induces more file descriptors kept open for longer, which in turn
may cause problems as wl_shm may be using a lot of file descriptors,
especially with Xwayland which can create a lot of pixmaps on behalf of
its X11 clients.
For platforms where mremap() is available, keeping those file
descriptors opened is a bit of a waste and may cause exhaustion of file
descriptors sooner that before commit
5a981ee8.
Only keep the mmap() file descriptor open on platforms which do not
implement mremap() and close it immediately as before on others.

wayland-shm: Check the size of sealed memory if ignoring SIGBUS handlers
In
11623e8f, SIGBUS handlers aren't set if F_SEAL_SHRINK is configured on
the memory. This helps avoid setting up handlers with cooperative clients;
however, if an application gives an incorrect size, the compositor would
access it anyways, figuring SIGBUS is impossible, and crash.
This can be fixed by simply removing the seal-checking logic and always
setting the signal handler. However, it seems that fstat can give the size
of the memfd, so we can check that the size we were told is within the
region. Since it's sealed to shrinking, it must never be shrunk in future,
so we can really (hopefully) ignore SIGBUS.
I was worried that fstat wasn't supported for this, but shm_overview(7) does
mention that it is a possible use.
The best solution would likely be avoiding SIGBUS entirely with
MAP_NOSIGBUS, but that hasn't been merged yet and wouldn't help systems
without it (e.g. with older kernels).
A proof-of-concept of this crash is attached with the merge request. Running
it with this patch gives an invalid-shm error, which is correct.

build: Include the Wayland minor version in libraries' ABI versions
The ABI of a shared library on Linux is given by a major version, which
is part of the SONAME and is incremented (rarely) on incompatible
changes, and a minor version, which is part of the basename of the
regular file to which the SONAME provides a symlink.
Until now, the ABI minor version was hard-coded, which means we can't
tell which of a pair of Wayland libraries is newer (and therefore
likely to have more symbols and/or fewer bugs).
libwayland-egl already had ABI major version 1, so we can use the
"marketing" version number as the ABI major.minor version number
directly, so Wayland 1.19.90 would produce
libwayland-egl.so.1 -> libwayland-egl.so.1.19.90.
libwayland-cursor and libwayland-server have ABI major version 0,
and OS distributions don't like it when there's a SONAME bump for no
good reason, so use their existing ABI major version together with
the "marketing" minor version:
libwayland-cursor.so.0 -> libwayland-cursor.so.0.19.90.
If the Wayland major version number is incremented to 2, we'll have to
rethink this, so add some error() to break the build if/when that
happens. Assuming that Wayland 2.0 would involve breaking changes,
the best way would probably to bump all the SONAMEs to
libwayland-foo.so.2.

protocol: Add wl_surface.offset
This is meant to address the issue where the call to 'wl_surface.attach'
is done by e.g. Vulkan, meaning applications cannot affect the values of
the offset passed as the x and y arguments.
The lack of ability to pass these is problematic when using the Vulkan
for e.g. drawing DND surfaces, as the buffer offset is used to implement
the drag icon hotspots.

server: stop wl_display event loop from any context
Calling wl_display_terminate() will exit the wl_display event loop
at the start of the next loop iteration. This works fine when
wl_display_terminate() is called after the event loop wakes up
from polling on the added event sources. If, however, it is
called before polling starts, the event loop will not exit until
one or more event sources trigger. Depending on the types of event
sources, they may never trigger (or may not trigger for a long time),
so the event loop may never exit.
Add an extra event source to the wl_display event loop that will trigger
whenever wl_display_terminate() is called, so that the event loop will
always exit.

kernel, so becomes more likely when the system is under load (e.g. running
