We really don't want to deal with sighups and pids. It's far easier
to just deal with the client destroyed signal to respawn the input method.
Inspiration taken from Pekka's commit 826dc14ec4
This fixes a potential crash on shutdown. If the input method client
pointer is still set (sighup handler hasn't run) but the client is
already destroyed, a call to text_backend_destroy() will try to destroy
the client a second time resulting in a segfault.

With multiple seats there are multiple bindings, so if the most recent

2. Check if transition is not null and if layout_transition_register was

3. Destroy transition if layout_transition_register was not ok, we can't
just free transition, we need to call layout_transition_destroy in

The problem with the old table of names is that it contains duplicates.
It is possible to end up with multiple outputs with the same name. In
that case you cannot write individual configurations for these outputs
in weston.ini, because they are matched by the name.
Change all names to follow the kernel naming scheme set in
drivers/gpu/drm/drm_crtc.c. The snprintf format now follows the kernel
style, too. Use the DRM_MODE_CONNECTOR_* macros rather than implicit
table ordering.
Completely new entries in the table are "Virtual" and "DSI".
There should not be any gaps in the macro values, but if there are, deal
with a NULL entry.
Also change "UNKNOWN" to "UNNAMED" so it's easier to distinguish from
"Unknown" by the kernel.
