We required GL headers for shl_gl.h. Even though the linker strips all the
GL dependencies if it's disabled during compilation, we still require it
as build-time dependency. Avoid that by not including shl_gl in any non-GL
builds.

Instead of generating C source files, we now use our binary-linker make
target which can link in any arbitrary binary file.
This way, we can delete genshader and instead link the files directly.
This speeds up compilation and makes the code more consistent.
We also strip the shaders from useless comments and whitespaces to reduce
memory consumption.

The genshader and genunifont utilities are run during the build process
to generate source files. In order for that to work when cross-compiling
the files need to be built using the native compiler instead of the
cross-compiler.
Add the AX_PROG_CC_FOR_BUILD m4 macro which defines various *_FOR_BUILD
variables that are the native equivalents of CC, CFLAGS, LDFLAGS, etc.
Override CC, CFLAGS and LDFLAGS for genshader and genunifont and their
object files so that they will be built natively and can be executed
during the build.

The ld.gold linker doesn't provide --format=default but needs --format=elf
instead. However, this doesn't work with ld.bfd. To avoid any linker
detection, we now link any binary file via partial-linking into a proper
object file itself and then link this object file in the final linking
step.
This also produces a fake libtool *.lo file so the libtool linking command
doesn't complain about PIC/non-PIC problems.

The VT subsystem manages the virtual VTs and registers them with the
seat/session-scheduler. They manage control and legacy nodes as they are
mostly the same.
The different contexts create these VTs and assign them to cdev clients.
This allows us to split the VT and cdev logic apart so they can be
assigned freely to different clients.

This introduces uvtd which replaces kmscon sessions as an external helper

UVT is based heavily on the old cdev-sessions. It uses CUSE/FUSE to
implement virtual terminals in user-space.
This move into a library allows to use it in other projects, too. There is
no reason to limit it to kmscon sessions. In fact, we will remove the
cdev-sessions, soon and make kmscon a stand-alone terminal emulator
without any session capability.
Instead, the uvtd program will provide the VT emulation.
This library is not finished, nor ready for use. However, feel free to
contribute patches so we can eventually release a stable API.

Instead of using the blown up UTERM_FORMAT_GREY binary data, we now use an
A1 1bit alpha channel and extract the data during runtime. This guarantees
that only used characters will be extracted into the full alpha channel.
We should add support for A1 formats in uterm to avoid this problem
entirely.
We also now link the binary file directly into the module via ld. This
avoids the long compile times for the huge C-array that we previously
generated. As a side effect, you no longer run out of memory linking this
file on small machines.
With this change we could even start making unifont a default font-backend
as it now works pretty well.

We need the font layer to build wlterm. However, the font layer depends on

The modesetting code of both DRM backends is almost the same so share it.
This also works around several race-conditions in some DRM drivers. In
particular, we cannot call drmModeSetCrtc while a drmModePageFlip is still
pending. Therefore, we wait for page-flips to complete before performing
an immediate mode-set.
This requires us to handle page-flip events synchronously so we can wait
for kernel page-flip events but the user-space bottom-half is executed in
an idle-handler.
Note that the chance that we have to wait for a page-flip to complete is
pretty small. In fact, without hacking the code to do fast page-flips, I
couldn't get kmscon to run into this condition.
Last but not least, this patch also makes the dumb-backend support
immediate page-flips like the DRM backend did all the time.
