Preparing for libweston and for the separation of the code base into
libweston vs. weston the compositor, we must remove all uses
weston_config structures from the backends. We have decided that all
option and config input happens in the compositor (main.c), and
configuration is passed in for the backends as structs.
Most other backends have already converted, and this patch converts the
DRM-backend to the libweston-style init API.
The libweston-style init API includes a header for each backend (here
compositor-drm.h) defining the configuration interface. The compositor
(main.c) prepares a configuration struct to be passed through libweston
core to the backend during initialization.
A complication with the DRM-backend is that outputs can be hotplugged,
and their configuration needs to be fetched from the compositor
(main.c). For this, the config struct contains a callback member. The
output configuration API is subject to change later, this is just a
temporary API to get libweston forward.
As weston_compositor's user_data was not previously used for anything,
and the output configuration callback needs data, the user_data is set
to the 'config' pointer. This pointer is only used in
drm_configure_output() in main.c.

With this struct versioning, it is possible to add new options without
breaking the ABI, as long as all additions are made to the end of a
struct and nothing existing is modified or removed. When things are
added, the structure's size will increase, and we'll use this size as
our minor version number. If existing things need to be changed, then
the major version, struct_version, is incremented to indicate the ABI
break.
From our call sites in main these major and minor version will be
recorded as struct_version and struct_size. Each backend will then
verify these against its own assumptions. So long as the backend's
struct is equal or larger than what was passed in and the major versions
are equal, we're good; but if it is larger, then this is a fatal error.

X11 is the only backend that still used the input event loop.
This patch is an identical rewrite of
6deb09ef8a which was then reverted in
3bebe6461a for reasons unrecorded. This
patch is also the revert of 22ba60e514.
Originally input devices were moved into their own event loop in
7ea10864c2 and the reason for that is
explained in 7dbf5e2ea7.
The idea behind the input event loop was that it would be beneficial to
process and relay input events to clients just once during an output
repaint cycle, because clients cannot update the image on screen any
faster anyway. All input events also carry a timestamp, so we didn't
lose any timing information. This was supposed to save power by reducing
the process wake-ups and context switches. There was also a mention of
reducing lag.
However, the concept of an output repaint loop does not really work out
when you have several outputs, but the input devices are not exclusive
to a certain output.
The logic for driving the input event loop in Weston core was written to
assume a single output. When you have multiple outputs with independent
repaint cycles, the input event loop handling becomes fairly random, one
output freezes input while another output thaws it, etc.
The DRM backend stopped using the input event loop when it started using
the libinput input backend, which became the default in
3f5e906268, and the old code was finally
ripped out in 823ad33ef3.
