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.
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.
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").
