protocol: replace pointer.attach with pointer.set_cursor
cursor: Add function for calculating current frame in cursor animation

Given a pointer to struct wl_cursor and an elapsed time in ms.,
wl_cursor_frame() will return the index of the cursor image the should
be displayed.
TODO: Remove cursor-as-regular-surface item
tests: Update test cases to new closure allocate convention
data-device: Fix list corruption when the source goes away

If the data source is destroyed, the corresponding offers may stay around for
a little longer (until the owning client destroys it).  When the offer is
finally destroyed, we have to be careful to only remove the source
destroy listener if the source hasn't yet been destroyed.

Thanks to Martin Minarik for tracking down where the corruption happened.
Xcursor: Don't ignore unknown file types

XFS doesn't return the file type with opendir(), and instead only
returns it when you stat() the file itself.  c66f2602 introduced a check
to ensure that only files and symlinks were loaded, while not checking
for DT_UNKNOWN.  Properly handle DT_UNKNOWN by just proceeding anyway.

wayland-cursor: Plug leak of filename on load_all_cursors_from_dir()
Maintain keyboard modifier state in wayland-server

Provide a slot for keyboard modifier state inside wl_keyboard for
implementations to update, and use this to send wl_keyboard:;modifier
events whenever the keyboard or pointer focus changes.

Send keyboard modifier event using the keyboard resource
Send modifier event to pointer focus when it changes too
configure.ac: Bump version to 0.94.90
wl_shell: Don't require that parent surfaces are wl_shell_surfaces

The set_transient and set_popup requests take a wl_shell_surface as
the parent surface argument.  We don't need the parent surface to be
a shell surface and this restricts the types of surfaces we can use
the transient and popup surface types on.
protocol: Change wording of pointer.set_cursor()

Change the description of pointer.set_cursor() so that a client without
pointer focus but that currently owns the pointer surface can update the
hotspot using it.
Allocate client proxy automatically for new objects

When the server send a new object ID, the client used to have to allocate
the proxy manually and without type-safety.  We now allocate the proxy
in a client-side post-processing step on the incoming closure.
wayland-server: reduce use of magic numbers

Make it clear what the significance of '5' and '113' actually is.
Also drop an unneeded function argument.
drop use of strerror()

It isn't thread-safe. Use the %m conversion specifier instead,
like the rest of the code already does.
wayland-server: fix fd leak on error path

And restructure get_socket_lock() so it's clearer that it's
allocating a new file descriptor.

Uncovered by an upcoming test.
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.
wayland-server: add more logging of errors
wayland-server: reject socket paths longer than 108 bytes

Attempting to write anything longer into the embedded char
array would create a non-null-terminated string, and all
later reads would run off the end into invalid memory.

This is a hard limitation of AF_LOCAL/AF_UNIX sockets.
