The Meson option "b_lundef" need to be set to false on FreeBSD, because
the symbol "environ" is in crt1.o, which is not linked with shared
libraries. With Meson >=0.48.0 it is possible to set this option only
for FreeBSD. This patch changes meson.build to do that.
External dependencies in Meson do not have include_directories,
therefore "includes: true" means nothing for the wayland-client partial
dependency. Because of this, the -I CFLAGs for wayland-client are not
used by the build command. This commit fixes this by using compile_args.
To prevent wl_keyboard keymap being written to by clients, use a unique
file descriptor for each wl_keyboard resource.

This commit allows outputs that need a CRTC to steal it from
user-disabled outputs. Note that in the case there are enough
CRTCs, disabled outputs don't loose it (so there's no modeset
and plane initialization needed after DPMS). CRTC allocation
still prefers to keep the old configuration, even if that means
allocating an extra CRTC to a disabled output.
CRTC reallocation now happen when enabling/disabling an output as
well as when trying to modeset. When enabling an output without a
CRTC, we realloc to try to steal a CRTC from a disabled output
(that doesn't really need the CRTC). When disabling an output, we
try to give our CRTC to an output that needs one. Modesetting is
similar to enabling.
A new DRM connector field has been added: `desired_enabled`.
Outputs without CRTCs get automatically disabled. This field keeps
track of the state desired by the user, allowing to automatically
re-enable outputs when a CRTC becomes free.
This required some changes to the allocation algorithm. Previously,
the algorithm tried to keep the previous configuration even if a
new configuration with a better score was possible (it only changed
configuration when the old one didn't work anymore). This is now
changed and the old configuration (still preferred) is only
retained without considering new possibilities when it's perfect
(all outputs have CRTCs).
User-disabled outputs now have `possible_crtcs` set to 0, meaning
they can only retain a previous CRTC (not acquire a new one). The
allocation algorithm has been updated to do not bump the score
when assigning a CRTC to a disabled output.
Layer surfaces are attached to edges of the screen starting with the youngest, causing new ones to always displace existing ones. This changes the order to oldest first, keeping the positions more often.
