This prevents from blocking shown in one display test. Also, it
makes sense to not proceed further in the code of the function
when an error ocurred.
v2. set errno
put note about the errno into wl_display_prepare_read doc
check for error with mutex locked
v3.
set errno to display->last_error
check for the error only in wl_display_read_events. It's sufficient
as prevention for the hanging and programmer doesn't need to
check if wl_display_prepare_read (that was previously covered by
this patch too) returned an error or the queue just was not empty.
Without the check, it could result in indefinite looping.
Thanks to Pekka Paalanen <pekka.paalanen@collabora.co.uk> for
