We will soon support custom swapchains. In order to track output damage
we should instead use the damage_ring which will hold all the buffers
we are currently tracking anyway across an arbitrary amount of swapchains.
We would fail to call scene_node_update() which would then call output
events for us. We need to make sure to update the node when we first map
a buffer, as the comment explained.
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.
- 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.
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.
