This patch follows a similar approach taken to detach the backends from
weston. But instead of passing a configuration struct when loading the
plugin, we use the plugin API registry to register an API, and to get it
in the compositor side. This API allows to spawn the Xwayland process
in the compositor side, and to deal with signal handling. A new
function is added in compositor.c to load and init the xwayland.so
plugin.
Also make sure to re-arm the SIGUSR1 when the X server quits.

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.

we're testing uninitialized values coming out of weston_compositor_pick_view.
This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.
This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.
Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them
safely for equality.
