Check the egl, glesv2 and gbm dependencies locally instead of relying on
the dep_* variables from the top level meson.build or
libweston/meson.build (dep_gbm).
This should make these dependencies now explicitly checked when the app
is built, rather than relying on other components doing the checks. If
the drm-backend was disabled, this would have probably hit an error
using the undeclared variable dep_gbm.

Helps people to avoid EGL and GLESv2 if they do not want them.
Stops using dep_egl and dep_glesv2 so that the human friendly error
message is alongside the dependency() statement, so that the message and
the statement can later be merged together once Meson offers the custom
error messages feature or something even more sophisticated.

Cairo is a hard dependency on the whole at least because tests seem to

Cannot use dependency() directly in the structure, because it will
execute regardless of the option. Instead, let's store the dependency
name in the structure and use the same logic as with simple_clients to
conditionally look for the dependencies.
As a bonus, this brings friendly error messages to demo-clients
dependencies.
subsurfaces' dependencies are also converted to maintain consistency
with simple_clients.

Remove IN_WESTON in favour of the already defined UNIT_TEST which is
used to modify a compilation unit to expose more functions for unit
tests to prod at.
Originally IN_WESTON meant that compilation unit was being compiled for
use in the Weston compositor, but it probably never really did anything
more than change what WL_EXPORT means in matrix.c.
This patch not only simplifies the logic, but it fixes the Meson build
of test-matrix: IN_WESTON was defined there even when matrix.c was being
built outside of Weston, which caused it to depend on libwayland
headers, which were not included in the Meson build of test-matrix.
Test-matrix has no reason to depend in libwayland in any way, so this
patch fixes that.

Add a client that uses EGL/GLESv2 to draw to dmabuf buffers, utilizing
EGLImages and FBOs. The client uses GBM to create the dmabufs buffers.
The simple-dmabuf-egl client is partly based on patch [1] that changes
dmabuf clients to use GBM instead of libdrm code, but has been greatly
simplified since in this case we don't require direct pixel access or
non-RGBA formats.

Previously weston-screenshooter was installed in LIBEXECDIR, but given
that now it can be invoked by the user whenever debug protocol is
enabled, let's intall it into BINDIR. This way, it can be invoked
without the need to modify PATH.

Screenshots of the outputs can only be taken by having a keyboard
plug-ed in, as to avoid potential malicious intent. On the other hand,
this is problematic as there are cases where a keyboard cannot
be used as a input device. A particular use-case is that for
multiple devices it can be cumbersome to connect a keyboard such
that using ssh can be much easier and can be further automated.
This patch allows taking screenshots without the need of having a
keyboard connected when debug protocol is enabled.
Add also a few words about the fact that this is a serious issue
and can lead to silently leaking the output contents.

As is stands now, libexec/weston-screenshooter can only be called from

Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.

There is often a need to print the name of a pixel format. Printing the
raw numeric value is hard to decipher, printing the four ASCII
characters is slightly more human-friendly but still needs a decoder
table. Add a name that can be printed easily.

It's a bit surprising that Weston looks different when launched from the root
of the git repo vs from elsewhere.
But it's also technically a security vulnerability: if I launch it from
a directory like /tmp, it might pick up a weston.ini created by another user,
which could then load modules with arbitrary code. Basically, it's the same
problem as including "." in $PATH.
