protocol: double-buffered state for wl_surface
This change breaks the protocol.
The current protocol is racy in that updates to surface content and
surface state (e.g. damage, input and opaque regions) are not guaranteed
to happen at the same time. Due to protocol buffering and handling
practices, the issues are very hard to trigger.
Committing damage to a surface at arbitrary times makes it hard to
track when the wl_buffer is being read by the server, and when it is
safe to overwrite (the case of wl_shm with a single buffer reused
constantly).
This protocol change introduces the concept of double-buffered state.
Such state is accumulated and cached in the server, unused, until the
final commit request. The surface will receive its new content and apply
its new state atomically.
A wl_surface.commit request is added to the protocol. This is thought to
be more clear, than having wl_surface.attach committing implicitly, and
then having another request to commit without attaching, as would be
required for a GL app that wants to change e.g. input region without
redrawing.
When these changes are implemented, clients do not have to worry about
ordering damage vs. input region vs. attach vs. ... anymore. Clients set
the state in any order they want, and kick it all in with a commit.
The interactions between wl_surface.attach, (wl_surface.commit,)
wl_buffer.release, and wl_buffer.destroy have been undocumented. Only
careful inspection of the compositor code has told when a wl_buffer is
free for re-use, especially for wl_shm and wrt. wl_surface.damage.
Try to clarify how it all should work, and what happens if the wl_buffer
gets destroyed.
An additional minor fix: allow NULL argument to
wl_surface.set_opaque_region. The wording in the documentation already
implied that a nil region is allowed.

Split the global registry into its own wl_registry object
The only way to make the global object listener interface thread safe is to
make it its own interface and make different listeners different wl_proxies.
The core of the problem is the callback we do when a global show up or
disappears, which we can't do with a lock held. On the other hand we can't
iterate the global list or the listener list without a lock held as new
globals or listeners may come and go during the iteration.
Making a copy of the list under the lock and then iterating after dropping
the lock wont work either. In case of the listener list, once we drop the
lock another thread may unregister a listener and destroy the callbackk
data, which means that when we eventually call that listener we'll pass it
free memory and break everything.
We did already solve the thread-safe callback problem, however. It's what
we do for all protocol events. So we can just make the global registry
functionality its own new interface and give each thread its own proxy.
That way, the thread will do its own callbacks (with no locks held) and
destroy the proxy when it's no longer interested in wl_registry events.

client: Add wl_event_queue for multi-thread dispatching
This introduces wl_event_queue, which is what will make multi-threaded
wayland clients possible and useful. The driving use case is that of a
GL rendering thread that renders and calls eglSwapBuffer independently of
a "main thread" that owns the wl_display and handles input events and
everything else. In general, the EGL and GL APIs have a threading model
that requires the wayland client library to be usable from several threads.
Finally, the current callback model gets into trouble even in a single
threaded scenario: if we have to block in eglSwapBuffers, we may end up
doing unrelated callbacks from within EGL.
The wl_event_queue mechanism lets the application (or middleware such as
EGL or toolkits) assign a proxy to an event queue. Only events from objects
associated with the queue will be put in the queue, and conversely,
events from objects associated with the queue will not be queue up anywhere
else. The wl_display struct has a built-in event queue, which is considered
the main and default event queue. New proxies are associated with the
same queue as the object that created them (either the object that a
request with a new-id argument was sent to or the object that sent an
event with a new-id argument). A proxy can be moved to a different event
queue by calling wl_proxy_set_queue().
A subsystem, such as EGL, will then create its own event queue and associate
the objects it expects to receive events from with that queue. If EGL
needs to block and wait for a certain event, it can keep dispatching event
from its queue until that events comes in. This wont call out to unrelated
code with an EGL lock held. Similarly, we don't risk the main thread
handling an event from an EGL object and then calling into EGL from a
different thread without the lock held.

Change filedescriptor API to be thread safe
The update callback for the file descriptors was always a bit awkward and
un-intuitive. The idea was that whenever the protocol code needed to
write data to the fd it would call the 'update' function. This function
would adjust the mainloop so that it polls for POLLOUT on the fd so we
can eventually flush the data to the socket.
The problem is that in multi-threaded applications, any thread can issue
a request, which writes data to the output buffer and thus triggers the
update callback. Thus, we'll be calling out with the display mutex
held and may call from any thread.
The solution is to eliminate the udpate callback and just require that
the application or server flushes all connection buffers before blocking.
This turns out to be a simpler API, although we now require clients to
deal with EAGAIN and non-blocking writes. It also saves a few syscalls,
since the socket will be writable most of the time and most writes will
complete, so we avoid changing epoll to poll for POLLOUT, then write and
then change it back for each write.

So if client will not free wl_data_source and start another drag'n'drop,

protocol: Add explicit nullable types
Most of the time it does not make sense to pass a NULL object, string, or array
to a protocol request. This commit adds an explicit “allow-null” attribute
to mark the request arguments where NULL makes sense.
Passing a NULL object, string, or array to a protocol request which is not
marked as allow-null is now an error. An implementation will never receive
a NULL value for these arguments from a client.

wayland-server: fix socket ownership race condition
Always unlink() the lock file before closing the file
descriptor for it. Otherwise, there is a race like this:
Process A closes fd, releasing the lock
Process B opens the same file, taking the lock
Process A unlinks the lock file
Process C opens the same file, which now no longer exists,
and takes the lock on the newly created lock file
Process B and C both 'own' the same display socket.
unlink()ing while holding the lock is effectively a better
way to release the lock atomically.
