compositor: Version the backend configuration structures

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.

compositor-x11: stop using input_loop

X11 is the only backend that still used the input event loop.

This patch is an identical rewrite of
6deb09ef8a72164947cdfa5f2414e292c7672c9c which was then reverted in
3bebe6461a9de5d8c5c7da0261c70cd250fa1fde for reasons unrecorded. This
patch is also the revert of 22ba60e514e074e4bdee1529aa8d22600712f001.

Originally input devices were moved into their own event loop in
7ea10864c2fc7370f5ada88a3fc91ab5f188da00 and the reason for that is
explained in 7dbf5e2ea744bde56b65ba45b935b77df4a783e1.

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
3f5e906268448f2d84b115c5f3d22165ce0021b1, and the old code was finally
ripped out in 823ad33ef34fa32b14b300d987fb9d2e2a42e9c4.

ivi-shell: call shell_surface_send_configure() directly

For some reason, it seems that ivi-layout.c has tried hard to avoid
calling directly into ivi-shell.c. This means there is a jump through
hoops just to get the configure event sent to the clients. Ivi-shell
registers a listener for a ivi-layout signal for sending the event.

Instead, let ivi-layout.c call directly into ivi-shell.c, and expose a
function to send out the configure events. This reduces some confusion
on who calls what.

The main idea though is that this makes ivi-shell.c not depend on struct
ivi_layout_surface fields directly anymore. In following patches,
ivi_layout_surface can be made opaque for ivi-shell.c.

both weston and xwayland consuming as much cpu as they can.

The simple fix is to just remove the test for text presence.

shell: Check more thoroughly for undefined surface resource

The surface can have an undefined resource in certain situations (such
as with xwayland).  So, since NULL is a valid state for this parameter,
and since the wl_resource_*, etc. calls require their parameters to be
non-NULL, make a practice of always checking the surface resource before
making wayland calls.

update v2:
  * Fix some c/p errors for pointer names
  * Drop null ptr check in add_popup_grab; probably redundant now
