If WAYLAND_DEBUG contains the token "thread_id", and gettid() is available, then include the current thread ID in the output from wl_closure_print. If multiple threads are sending requests, then those requests can get interleaved. That's usually fine, but for wl_surface requests and commits, that can cause problems ranging from incorrect behavior to protocol errors. Being able to see which requests are sent by different threads would make such problems much easier to diagnose. Signed-off-by: Kyle Brenneman <kbrenneman@nvidia.com>
