The only reason why we have both weston_compositor_tear_down() and
weston_compositor_destroy() is that the only we had to destroy
the log context was keeping weston_compositor alive and calling
weston_log_ctx_compositor_destroy().
After commit "weston-log: replace weston_log_ctx_compositor_destroy()
by weston_log_ctx_destroy()", it's not necessary to keep a zombie
weston_compositor just to be able to call
weston_log_ctx_compositor_destroy().
Fold weston_compositor_tear_down() into weston_compositor_destroy(),
as this split is useless now.

The function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a
weston_log_context unlinked from a weston_compositor and currently there
is no way to destroy it.
Add function weston_log_ctx_destroy(), what makes the destruction of
weston_log_context independent of weston_compositor.
With this change, one could destroy a weston_compositor and keep the
related weston_log_context (since now weston_log_context can be destroyed
without the need of a weston_compositor). But if weston_compositor gets
destroyed it's also necessary to destroy weston_log_context::global,
as the debug protocol depends on the compositor. So a listener has been
added to the destroy signal of weston_compositor.

When option-parser is confronted with a boolean option, have it write a
bool rather than treating the value as a pointer to an int32.
(lib)weston already heavily uses bool types internally, so this has the
nice side effect of eliminating quite a few local variables which only
existed as integer shadows of internal boolean variables.

This takes everything that was in 'weston' the executable a turns it into
library. A new trivial 'weston' executable is written.
Creating the library will allow future improvements:
- we can link weston plugins against the library, meaning that they no longer
need unresolved symbols to be allowed during linking
- tests do not have to fork() and exec() 'weston', they can just link to the
library and call wet_main() after setting things up; this will help with
using a debugger
install_rpath is set so that we can install the library into weston's module
directory, away from the normal libraries in a system. This is one library we
do not intend for others to use.
The library has no stable ABI and is not versioned.

When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.
This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.
The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

When hotunplugging a display, the compositor will tear the top-level
wet_output object down, freeing its memory.
However, destruction of the backend output might be delayed in certain
situations (e.g. destroying DRM output while in the middle of a page
flip).
When the backend output is finally destroyed, it will trigger a
destruction callback previously added by the compositor, which point to
data belonging to the top-level wet_output object.
In order to avoid access to invalid data when the backend output is
destroyed after the top-level wet_output object, remove the destruction
callback from the corresponding list before freeing the object.

It is quite similar to the remoting plugin. It just exports the frames via
pipewire instead of the builtin GStreamer pipeline.
It implements the same virtual output API. Virtual outputs can be created
by adding 'pipewire-output' sections to weston.ini.
The generated frames can be accessed with any pipewire client. e.g. with
GStreamer:
gst-launch-1.0 pipewiresrc ! video/x-raw,format=BGRx ! ...

Destroying the compositor after destroying the log scope will not print
out the messages in the tear down/clean-up phase of the compositor, so
add a new tear_down function which allows keeping a valid reference to
the compositor. This way we can destroy the compositor before destroying
the scope and keep the debug messages.
While at it remove the log context destroy part from the clean-up
of the compositor and make it stand on its own.

The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).
While there, fix some minor indentation issue.

The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.
The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

This is so that, for instance, people using weston as their main Wayland
compositor can invert the sense of two finger scrolling or change
pointer acceleration using weston.ini, rather than having to edit C
code.
All of the options that libinput itself exposes through its API are now
exposed in weston.ini. The new options are called `tap-and-drag`,
`tap-and-drag-lock`, `disable-while-typing`, `middle-emulation`,
`left-handed`, `rotation`, `accel-profile`, `accel-speed`,
`scroll-method`, `natural-scroll`, and `scroll-button`. I have
successfully tested everything except for `rotation`, out of a lack of
hardware support.
weston now depends directly on libevdev for turning button name strings into
kernel input codes. This was needed for the `scroll-button` config
option. (weston already depends indirectly on libevdev through
libinput, so I figured people would be OK with this.) As a practical
matter for debian-style packagers, weston now has a build dependency on
libevdev-dev.
Right now, the code applies the same options to all attached devices
that a given option is relevant for. There are plans for multiple
[libinput] sections, each with different device filters, for users who
need more control here.
