This adds a public header so that applications can get the Wayland
version number at compile time. This can be used to make applications
that support compiling against multiple versions of Wayland.
There is a separate installed header called cogl-version.h which gets
included by both wayland-client.h and wayland-server.h
The canonical place for the version number is the configure.ac script
which splits it into three separate m4 defines for the major, minor
and micro version. These are copied into the generated
wayland-version.h header using AC_SUBST. There is also a string form
of the complete version number.
The version number is now also automatically copied into the two .pc
files.
Because the major, minor and micro parts are required it is no longer
possible to leave the version number as 'master' when building from
git. Most projects seem to immediately bump the git repo to a fake
version number (usually odd) after making a release so that there is
always a relative number that can be used for comparison. This patch
sets the git version to 0.99.0 under the assumption that the next
release will be 1.0.0.
The wayland protocol, as X, uses timestamps to match up certain
requests with input events. The problem is that sometimes we need to
send out an event that doesn't have a corresponding timestamped input
event. For example, the pointer focus surface goes away and new
surface needs to receive a pointer enter event. These events are
normally timestamped with the evdev event timestamp, but in this case,
we don't have a evdev timestamp. So we have to go to gettimeofday (or
clock_gettime()) and then we don't know if it's coming from the same
time source etc.
However for all these cases we don't need a real time timestamp, we
just need a serial number that encodes the order of events inside the
server. So we introduce a serial number mechanism that we can use to
order events. We still need real-time timestamps for actual input
device events (motion, buttons, keys, touch), to be able to reason
about double-click speed and movement speed so events that correspond to user input carry both a serial number and a timestamp.
The serial number also give us a mechanism to key together events that
are "logically the same" such as a unicode event and a keycode event,
or a motion event and a relative event from a raw device.
There's a big cost to setting up and tearing down a mmap and faulting in
the pages to back it. For cases where we're continuously reallocating
shm wl_buffers (resizing a surface, typically) it is a big performance
improvement to be able to reuse a mmap area. This change makes the shm
buffer allocation a two step process: first allocate a wl_shm_pool, then
allocate a buffer from the pool. The wl_shm_pool encapsulate the shared
memory pool, and lets clients allocate wl_buffers backed by chunks of that
memory. Buffers are allocated at an offset into the pool, so it's possible
to create multiple buffers from one pool, for example for icons or cursor
images.
wl_input_device::grab_button is unsigned but the button parameter to
wl_grab_interface::button is signed. This lead to a warning in
data-device.c.
The button number is unsigned in the protocol, so make it unsigned in
the wl_grab_interface API, too. Fixes the compiler warning "comparison
between signed and unsigned integer expressions".

The variables opcode and size were unsigned, which lead to warnings
about comparisons of signed vs. unsigned.
Change these variable to signed. Their usage never relies on being
unsigned.
This also fixes (an assumed) printf format string problem, where these
were printed with %d, not %u.

This adds more gcc warnings that should be useful, and suppresses the
unused parameter warnings that are not wanted.
Most importantly, this change enables warnings about comparison between
signed and unsigned.

And remove the .tex file
Minor changes:
- where the .tex file had some interface descriptions, the docbook source
now links to the actual protocol. The exception here is the shared object
cache which is simply a <programlisting> until the protocol spec exists.
- "Implementation" section skipped, this seems in need of an update anyway
and may be better documented elsewhere (wiki?)

Wrap all tests with a memory balance check to detect potential
memory leaks.
Fixed a few tests that had memory leaks contained in the tests
themselves.

Instead of directly freeing an event source upon removal put it in a
queue later handled by the event loop; either after a dispatch or upon
event loop destruction.
This is necessary to avoid already queued up event sources to be freed
during some other dispatch callback, causing segmentation faults when
the event loop later tries to handle an event from the freed source.
