This reverts commit 2396aec684.
This exact version of the sub-surface protocol has been copied into
Wayland core. Therefore it must be removed from here to avoid build
conflicts and useless duplication.
No other changes to sub-surface protocol consumers are needed, the
identical API is now offered by libwayland-client and libwayland-server.
The commit adding sub-surfaces to Wayland is:

weston_view_update_transform() will post damage in the old and new
positions of the view and thus make sure we always repaint properly.
In particular, in bug 66133, the test suite moves the surface off
any output and weston_surface_schedule_repaint() in commit fails to
do anything, since the surface is not on any output.
After changing view geometry, we have to either call
weston_compositor_schedule_repaint(), which is what shell.c typically
does, though that repaints all outputs, or call
weston_view_update_transform() to force update the transformation
and queue repaints on affected outputs.
https://bugs.freedesktop.org/show_bug.cgi?id=66133
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

This tests (via the table-driven testing method) that the correct
number of vertices and also the correct vertices themselves
are generated for an clip box and polygon of up to eight vertices.
Also add a libshared-test.la so that we don't have to build weston-test-runner
all the time
The new TEST_P macro takes a function name and a "data" argument to
point to an arbitrary array of known size of test data. This allows
multiple tests to be run with different datasets. The array is stored
as a void * but advanced by a known size on each iteration.
The data for each invocation of the test is provided as a "data" argument,
it is the responsibility of the test to cast it to something sensible.
Also fixed single-test running to only run the tests specified
check_PROGRAMS and friends are only built during make check. Which is a
great way of introducing compiler errors in tests. Always build them, TESTS
defines what's being run during make check.
Now that we use AC_SYS_LARGEFILE, we need to pull in config.h at least
whereever we use mmap(). Fixes at least the test-suite and simple-shm
on 32 bit systems.
This commit sets the version numbers for all added/created objects. The
wl_compositor.create_surface implementation was altered to create a surface
with the same version as the underlying wl_compositor. Since no other
"child interfaces" have version greater than 1, they were all hard-coded to
version 1.

This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config. This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.
To avoid a TOCTOU race the config file is actually open()ed during the
search. Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.

Add protocol for sub-surfaces, wl_subcompositor as the global interface,
and wl_subsurface as the per-surface interface extension.
This patch is meant to be reverted, once sub-surfaces are moved into
Wayland core.
Changes in v2:
- Rewrite wl_subcompositor.get_subsurface description, and move mapping
and commit details into wl_subsurface description. Check the wording
in wl_subsurface.set_position description.
- Add wl_subsurface.set_commit_mode request, and document it, with the
commit_mode enum. Add bad_value error code for wl_subsurface.
- Moved the protocol into Weston repository so we can land it upstream
sooner for public exposure. It is to be moved into Wayland core later.
- Add destroy requests to both wl_subcompositor and wl_subsurface, and
document them. Experience has showed, that interfaces should always
have a destructor unless there is a good and future-proof reason to not
have it.
Changes in v3:
- Specify, that wl_subsurface will become inert, if the corresponding
wl_surface is destroyed, instead of requiring a certain destruction
order.
- Replaced wl_subsurface.set_commit_mode with wl_subsurface.set_sync and
wl_subsurface.set_desync. Parent-cached commit mode is now called
synchronized, and independent mode is desynchronized. Removed
commit_mode enum, and bad_value error.
- Added support for nested sub-surfaces.

move_client() needs to attach the buffer, even if it was attached already,
because since 184df50 configure() will be called only on newly attached
surfaces, but the one that sets the test surface position is the configure
function.
This way the shell can know when a surface has been unmapped by
checking the value returned by weston_surface_is_mapped(surface).
The configure handlers have now width and height parameters, so
they do not need anymore to check manually the buffer size.
If a surface's buffer is NULL the width and height passed to the
configure are both 0.
Configure is now only called after an attach. The variable
weston_surface.pending.newly_attached is set to 1 on attach, and
after the configure call is reset to 0.
This patch installs the three header files that define the compositor
plugin interface as well as a pkg-config file. This allows
building weston plugins outside the weston tree. We currently don't make
any guarantees about the plugin API/ABI except that within a stable
branch we won't break it.
Tests especially, that attach-attach-commit does not result in a release
of the first buffer.
Also tests, that the old buffer is released when a new buffer has been
attached, committed, and displayed (frame callback).

We handle FAIL_TEST tests by simply inverting the success flag. The
problem with this is, that if a FAIL_TEST fails by a SIGSEGV, it will be
interpreted as passed. However, no code should ever cause a SEGV, or any
other signal than ABRT. And even ABRT only in the case of an assert()
that is meant to fail. We would probably need more sophistication for the
FAIL_TEST cases.
For now, just interpret any other signal than ABRT as a hard failure,
regardless whether it is a TEST or FAIL_TEST. At least segfaults do not
cause false passes anymore.

Without this we try to load the installed backends, which is nasty for
regular runs, and just doesn't work for make distcheck, which sets
prefix to $PWD/_inst. This makes sure we load the right backend
and make distcheck pass. Other modules (xwayland, shells etc) just don't
get loaded for distcheck and for make check we still try to load the
installed modules.
Add a macro that wraps wl_display_roundtrip() and check for errors. It
is a macro, so that the assert would show the relevant file and line
number.
This will also catch protocol errors, that would go unnoticed otherwise.
All roundtrips in tests are replaced with the check.

This cleans up the 'make check' output considerably. When all goes well,
you will only see the "PASS" line for each of $TESTS.
Weston logs into a separate file than stdout and stderr, so server logs
end up in one file per test, and other output to another file per test.
'make distclean' does not remove the tests/logs/ directory.
Also changes the weston-tests-env interpreter to bash, since I think &>
and ${1/.la/.so} might be bashisms.
The remaining module tests don't need to fork and talk to a test client,
so just convert them to regular modules and let them handle running their
tests themselves. Then drop test-runner.[ch].
This test case is the last user of the test-client code and it only
tests launching the test-client. In other words it's a minimal test
of the framework we're dropping, so just drop this test.
Remaining use case was when we move the pointer. This doesn't change
geometry so we can just use a wl_display_roundtrip() to make sure
we get the request to the server and receive the resulting events.
As for button-test, a wl_display_roundtrip is sufficient here. The
yield() between wl_test_activate_surface() and wl_test_send_key() is
also not needed, since the two requests will arrive at the server in
order, and will activate the surface first, then send a key event.
A round trip is sufficient here. We need to make sure that the server
has received the wl_test request and that we've received the event
that the request triggers. The wl_display_roundtrip() helper does
exactly that: it sends a wl_display.sync request, which will hit the
server after the wl_test requests and thus the wl_callback.done event
will come back after the server has seen all the previous requests and
after we've handled all preceeding event.
When moving a test surface, use a frame callback to make sure the
surface has been moved and the geometry updated. The compositor may
delay updating the transform matrices, but once we get the frame
callback we know the surface has been repainted and the geometry
updated.
This adds a weston-test-runner for the weston test extension and
some weston test client helper methods.
Converted keyboard-test to use the new test interface, runner,
and helper methods.

Since the send-button-state request comes in on one socket and the
wayland event we're looking for comes in on another socket, the order
that we process the two in is undefined. Thus, button-test fails
intermittently, depending on which event we process first.
We change wl_display_flush() to wl_display_roundtrip(), to make sure that
we deal with all wayland events before handling test protocol requests.
In seat_handle_capabilities, if input->pointer is not properly
initialized, then it will contain an arbitrary value and results
in the wl_pointer listener not getting registered if that value
is not 0/null. Thus, use calloc to initialize the "input" instance.

Also make all the callers of weston_surface_assign_output() update the
transform instead. This makes sure that when the surface is assigned an
output its bouding box is valid.
This fixes a bug where a newly created surface would have a NULL output
assigned. This would cause weston_surface_schedule_repaint() to not
schedule a repaint, preventing the surface to be shown until something
else caused a repaint.

wl_input_device has been both renamed and split. wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.
It now only generates one event: to let clients know that it has new
capabilities. It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.
This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat). Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.
For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.
