scan-build is a little confused, thinking xwm->xres value could change
during the execution of xwayland_surface_create so client_id_cookie
could end up used uninitialized.
The struct is just an unsigned int, so no harm in initializing it to get
it off the list.
In query_modifier_support, the calloc for either or both of render_mods
and texture_mods may fail, in which case both are freed for convenience.
However, if one is non-NULL, vulkan_format_props_finish will try to free
it again.
NULL them to avoid double-free.
If drm_format_set_extend fails, we need to make sure each wlr_drm_format
is cleaned up together with the formats array. Finish the set to take
care of it.
On startup, we fetch the previous MODE_ID blob ID so that
compositors can keep using the previous mode if they want to.
However, that blob doesn't belong to us, it belongs to the
previous DRM master. As a result, we get an error when trying to
destroy it.
Fix this by tracking whether the blob belongs to us or not.

Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead,
require POSIX.1-2008 globally. A lot of core source files depend
on that already.
Some care must be taken on a few select files where we need a bit
more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and
some files need BSD extensions (_DEFAULT_SOURCE). In both cases,
these feature test macros imply _POSIX_C_SOURCE. Make sure to not
define both these macros and _POSIX_C_SOURCE explicitly to avoid
POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001
but _XOPEN_SOURCE says POSIX.1-2008).
Additionally, there is one special case in render/vulkan/vulkan.c.
That file needs major()/minor(), and these are system-specific.
On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need
to make sure it's not defined for this file. On Linux, we can
explicitly include <sys/sysmacros.h> and ensure that apart from
symbols defined there the file only uses POSIX toys.
If all connectors and planes already have the right CRTC set, or
are disabled, we can skip the device-wide reset after a VT switch.
I've contemplated using a more fine-grained logic to only reset
the connectors, CRTCs and planes that need to be migrated. However,
writing a correct algorithm for this would be quite involved, and it
doesn't seem worth the trouble anyways.

This function fetches property IDs. These don't change for the
lifetime of the connector. Instead of refreshing the property IDs
on hotplug (and leaving property IDs unset for disconnected
connectors), only fetch the property IDs when we create the
connector.
- Add POSIX 1993.09 compliance macro in source files that use
"struct timespec";
- Add POSIX 2001.12 compliance macro in source files that use
"struct sigaction" and the SA_SIGINFO macro, or the fchmod()
function;
- Add POSIX 2008.09 compliance macro in source files that use the
getline() function.
These compliance macros are enough for wlroots to compile with the
git-master version of uClibc-ng.

This implements the new ext-foreign-toplevel-list-v1 protocol [1].
Implemented analog to the zwlr-foreign-toplevel-management-v1 implementation.
The additional _ext_ in the names was added to avoid name collisions.

Compositors now are expected to wait for an initial commit by checking
wlr_xdg_surface.initial_commit on every surface commit and send
(schedule) configure events manually.
Since we only use the backend capabilities here we can simply pass
them in directly. This allows other locations to create an allocator
even if they don't have a backend. They can simply specify the caps
they want instead.
Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block
info. However, it doesn't make sense to store them in
wlr_pixel_format_info, as they will never be useful (currently, this
info is used for shm, which doesn't have a concept of multi-planar
buffers.)
Let's define a separate array and function for determining whether a
pixel format has alpha.
