Add more POSIX compliance macros to fix uClibc support
- 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.

d368028bd5 allocator: remove backend parameter in allocator_autocreate_with_drm_fd
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.

4ad6e6c298 backend: destroy multi backend when primary backend is
This makes it easy for compositors to handle situations where the
DRM or libinput backend becomes unavailable. Compositors can listen
the destroy event of the multi backend returned by
wlr_backend_autocreate() and decide what to do.

a82fc4cb8f backend/multi: emit destroy signal before destroying child backends
Some users might want to destroy the multi backend when a child
backend is being destroyed. However, they can't destroy the multi
backend if it's already in the process of being destroyed.

The destroy signal was changed to be emitted after destroying child
backends in babdd6ccf7 ("backend: fix use-after-free when destroying
backends"). However, this was done to accomodate for an old
"output_remove" event on backends, which has long been dropped in
favor of wlr_output.events.destroy.

This patch follows the same principle as 5d639394f3
("types/output: emit destroy event before destroying global").

f81c3d93cd backend/drm: save current refresh rate

instead.

d8c0707e27 backend/drm: return secondary backend DRM FD
It can be useful for compositors to get the real DRM FD instead of
the one from the parent compositor. For instance, some compositors
might want to perform some DRM IOCTLs there to check the driver
name, fetch some DRM resources, etc. This will also be a requirement
for direct scanout on secondary GPUs.

ae3d7a697c backend/drm: use DRM_IOCTL_MODE_CLOSEFB instead of RMFB
RMFB implicitly performs a modeset to turn off any CRTC which is
using the FB. This prevents seamless transitions between two DRM
masters from working.

Use the new CLOSEFB IOCTL which doesn't turn off anything and leave
it up to the compositor to turn off outputs on shutdown if it wants
to.

4990ed99eb backend/x11: don't send ConfigureRequest with the same size
Under X11, ConfigureNotify means that the window has already been resized.
Sending ConfigureRequest with the received size is not only useless, but also
can confuse the window manager, which will probably reply with the current
(i.e. *old*) size causing a configure loop.

63792b38e4 backend/session: take wl_event_loop instead of wl_display
wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.

Switch to wl_event_loop to better reflect the above.

3b53d1cbf1 backend/drm: introduce page-flip tracking struct
Introduce a per-page-flip tracking struct passed to the kernel
when we request a page-flip event for an atomic commit. The kernel
will pass us back this pointer when delivering the event.

This eliminates any risk of mixing up events together. In particular,
if two events are pending, or if the CRTC of a connector is swapped,
we no longer blow up in the page-flip event handler.
