This (so-far) Linux-only API lets users create file descriptors purely
in memory, without any backing file on the filesystem and the race
condition which could ensue when unlink()ing it.
It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.
This patch is best viewed with the -w option of git log -p.
It is an almost exact copy of Wayland commit

Using the parent '../' path component in #include statements makes
the codebase more rigid and is redundant due to proper -I use.

Mostly remove headers that aren't actually needed for anything.
Add stdint.h to permit dropping xf86drm.h, which is otherwise unneeded.

bad-buffer-test is FAIL_TEST and every assert() (or even SIGSEGV signal)
make it pass. It shouldn't be so for example when assert() is invoked
when a client couldn't connect to display.
Make sure that only relevant asserts make the test pass
and the other make it fail (by returning 0)
There was an issue recently in screen-share.c where config.h was not
being included, resulting in the wrong definition for off_t being used on
32 bit systems. I checked and I don't think this problem is happening
elsewhere, but to help avoid this sort of problem in the future, I went
through and made sure that config.h is included first whenever system
headers are included.
The config.h header should be included before any system headers, failing
to do this can result in the wrong type sizes being defined on certain
systems, e.g. off_t from sys/types.h

This tests the wl_shm buffer access wrappers, that are supposed to catch
the invalid accesses to a memory-mapped file beyond EOF.

Add a macro that wraps wl_display_roundtrip() and check for errors. It
is a macro, so that the assert would show the relevant file and line
number.
This will also catch protocol errors, that would go unnoticed otherwise.
All roundtrips in tests are replaced with the check.

Remaining use case was when we move the pointer. This doesn't change
geometry so we can just use a wl_display_roundtrip() to make sure
we get the request to the server and receive the resulting events.
A round trip is sufficient here. We need to make sure that the server
has received the wl_test request and that we've received the event
that the request triggers. The wl_display_roundtrip() helper does
exactly that: it sends a wl_display.sync request, which will hit the
server after the wl_test requests and thus the wl_callback.done event
will come back after the server has seen all the previous requests and
after we've handled all preceeding event.
