a81435ab5f cogl: Remove CoglBool, use gboolean instead
This basically reverts commit 54735dec, which tried to avoid the
GLib-defined types in favor the standard C ones. One exception to this
is the bool type, for which the commit introduces a new type CoglBool.

Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of `int`) are completely compatible with bool (size `char`).

dbe73c3296 meson: Do not install cogl config.env if installed tests are disabled
Until meson 0.50, setting the install parameter in 'configure_file' is ignored
if 'install_dir' is set. Then until mutter doesn't depend on such meson version
cogl_installed_tests_libexecdir should be empty unless have_installed_tests is
false, or this file will be installed anyway.

5c3ec27b4b cogl: Fix builds with G_DISABLE_ASSERT
Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

7f551ba776 meson: Don't list libraries private dependencies in pc files
pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.

So list packages needed only by mutter itself inside *_pkg_private_deps and
don't expose such packages to pkg-config, but only use them at build time.

54685091f1 cogl-path: Remove own glu.h version
cogl-path uses types from glu.h, but to avoid a build dependency on glu,
it kept a minified copy of glu.h in tree. Drop this file and just use
the actual glu.h. To avoid linking to libGLU.so, just use the
includepath, instead of actually adding glu as a real dependency.

This means we can remove an includepath meant to make it possible to
include <GL/glu.h>.

Drop Autotools
I saw Meson fade from the sky
On the wind I heard a sigh
As snowflakes cover fallen Makefiles
I will say this last goodbye

Meson is now coming
So ends Autotools days
Future is now coming
And we must away
Over Python and without Bashisms
Through lands where never Meson touched
By silver streams that run down to the Sea

Under parsers, beneath old legacy
Over snow one winter’s morn
I turned at last to paths that lead home
And though where the road then takes me
I cannot tell
We came all this way
But now comes the day
To bid you farewell

Many places I have been
Many sorrows I have seen
But I don’t regret
Nor will I forget
All Makefiles that took that road with me

I bid you all a very fond farewell.

d360b25b81 build: Install .pc files in correct location
If a library is provided in the positional arguments, then meson
defaults to installing the .pc file in a 'pkgconfig' subdirectory
in the library's install location. We want the files in the regular
$libdir/pkgconfig rather than $libdir/mutter-$api/pkgconfig, so
specify the location explicitly in the parameters.

c681ccef3c cogl/texture-2d-gl: Bind correct target when getting data
While for normal textures, GL_TEXTURE_2D should be used, when it's an external
texture, binding it using GL_TEXTURE_2D results in an error.

Reading the specification for GL_TEXTURE_EXTERNAL_OES it is unclear whether
getting pixel data from a texture is possible, and tests show it doesn't result
in any data, but in case it would eventually start working, at least bind the
correct target for now.

Add Meson support for installed tests
This is the last remaining feature necessary to achieve
parity with the Autotools build.

A few changes were made to the install locations of the
tests, in order to better acomodate them in Meson:

 * Tests are now installed under a versioned folder (e.g.
   /usr/share/installed-tests/mutter-4)

 * The mutter-cogl.test file is now generated from an .in
   file, instead of a series of $(echo)s from within Makefile.

Notice that those tests need very controlled environments
to run correctly. Mutter installed tests, for example, will
failed when running under a regular session due to D-Bus
failing to acquire the ScreenCast and/or RemoteScreen names.

cogl/tests: Use tmp file to dump test results
When running installed tests, the working directory for Cogl
tests is /usr/libexec/installed-tests/mutter-cogl-4/conform,

To avoid the adding stray hidden files to the current directory,
adapt the runner script to fallback to $(mktemp) - which is
available on all platform we care about - and avoid adding
hidden files everywhere.

981b045459 cogl: Pick glReadPixels format by target, not source
Presumably glReadPixels itself can be more performant with pixel format
conversions than doing a fix-up conversion on the CPU afterwards. Hence,
pick required_format based on the destination rather than the source, so
that it has a better chance to avoid the fix-up conversion.

With CoglOnscreen objects, CoglFramebuffer::internal_format (the source
format) is also wrong. It is left to a default value and never set to
reflect the reality. In other words, read-pixels had an arbitrary
intermediate pixel format that was used in glReadPixels and then fix-up
conversion made it work for the destination.

The render buffers (GBM surface) are allocated as DRM_FORMAT_XRGB8888.
If the destination buffer is allocated as the same format, the Cogl
read-pixels first converts with glReadPixels XRGB -> ABGR because of the
above default format, and then the fix-up conversion does ABGR -> XRGB.
This case was observed with DisplayLink outputs, where the native
renderer must use the CPU copy path to fill the "secondary GPU"
framebuffers.

This patch stops using internal_format and uses the desired destination
format instead.

_cogl_framebuffer_gl_read_pixels_into_bitmap() will still use
internal_format to determine alpha premultiplication state and multiply
or un-multiply as needed. Luckily all the formats involved in the
DisplayLink use case are always _PRE and so is the default
internal_format too, so things work in practise.

Furthermore, the GL texture_swizzle extension can never apply to
glReadPixels. Not even with FBOs, as found in this discussion:
https://gitlab.gnome.org/GNOME/mutter/issues/72
Therefore the target_format argument is hardcoded to something that can
never match anything, which will prevent the swizzle from being assumed.

6502735f01 cogl: Remove mesa_46631_slow_read_pixels_workaround
This function gets hit even today on relatively modern Intel systems (I
have a Haswell Desktop with Mesa 18.2.4) if the pixel format is right.
Presumably it makes things slower for no longer a reason.

According to cb146dc515, this
functionality was refactored into a workaround path in 2012. The commit
message mentions the problem existing before Mesa 8.0.2. The number
refers to https://bugs.freedesktop.org/show_bug.cgi?id=46631 .

The use case where I hit this is when improving support for DisplayLink
video outputs. These are used through a "secondary GPU", and since
DisplayLink does not have a GPU, Mutter uses the CPU copy path with Cogl
read-pixels[1]. If the DisplayLink framebuffer was allocated as
DRM_FORMAT_XRGB8888 (the only format it currently handles correctly),
mesa_46631_slow_read_pixels_workaround would get hit. The render buffer is
the same format as the framebuffer, yet doing the copy XRGB -> XRGB ends
up being slower than XRGB -> XBGR which makes no sense.

This patch is not sufficient to fix the XRGB -> XRGB copy performance,
but it is required.

This patch reverts CoglGpuInfoDriverBug into what it was before
cb146dc515.

[1] This is not actually true until
    https://gitlab.gnome.org/GNOME/mutter/merge_requests/278 is

4139907a7e cogl: Ensure to only clear the depth buffer if depth testing is enabled
The depth buffer is marked as invalid when 1) the framebuffer is just created,
and 2) whenever GL_DEPTH_TEST is enabled on it. This will ensure the
framebuffers attached depth buffer (if any) is properly cleared before it's
actually used, while saving needless clears while depth testing is disabled
(the default).

7d20101198 cogl-framebuffer: Remove swap_throttled config
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.

In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.

Removing it means less code, less branches when running,
and one less config option to deal with.

This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

This commit includes following fixes for a few shell scripts:

2. Replace `command` with $(command) because the latter is easier to use

ef85d1a643 Add meson build support
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.

There are some differences between the autotools setup and the new
meson. Here are a few:

The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.

The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.

Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
