While exiting, on the shutdown compositor path, for instance if we don't have
permission access to create a lock file we will end up reporting some memory
leaks/use-after-free.
This patch addresses of all them:
- api->listen returns NULL and we do not property free wet_xwayland
struct
- we don't remove the signal handler causing a use-after-free (signal
handler gets called by the main object has been freed)
- we don't remove/destroy the debug scope causing a mem-leak
- on the same path check for valid event source to avoid deref invalid
pointers.
Add a simple wrapper which we can call in other call sites.

This is problematic as we don't have namespacing for these and some of
the macros can interfere with other defines.
This reverts commit 8634c7e349.

As weston_windowed_output_get_api needs ARRAY_LENGTH() move helpers to a
libweston/ so other users can re-use that instead of re-defining these
all over. Easier for other front-ends to make use of them.
With this change windowed-output-api.h also includes the helpers header.
