We no longer need these helpers so remove them. We require each backend to
register itself as part of module-loading so no need to keep these

Similar to the font backends we now require one backend to be always
available as safe fallback. The bblit backend is the most basic backend so
make it mandatory and link it unconditionally.

The freetype2 backend is no longer recommended. You should always prefer

The owner fields specifies the module that provides the code for the given
backend. The font-core is responsible of ref/unref'ing the module so its
code is always available as long as the module exists.
We cannot push this into the modules as modules _must_ never call
kmscon_module_unref(KMSCON_THIS_MODULE)! Because this might drop the last
reference and hence the function might disallocate the module. However,
this means that it cannot return because the caller is _part_ of the
module and so no longer valid.

Several parts of kmscon have huge external dependencies. However, we allow
them to be disabled during build-time. But this is not enough as it
requires distributions to choose which options to use. Therefore, we now
allow dynamicly loadable modules that can optionally be installed and
kmscon automatically picks them up.

Each font-backend now also gets a .finalize callback that is called when
the last font-user drops its font. This will allow modules to destroy
themself when the last reference is dropped.

The new destroy callback is called whenever an entries last reference is

With modules we no longer need to conditionally load backends. Instead
each module will register the backend with the main application on load.
This will temporarily break pango, freetype2 and unifont backends as they
are not registered until we introduce full module support.

We want to modularize the text-font library, so we need each backend as a
different library. This step links each of them into a different static
library so we can now link them either into the binary or into modules.
This step also makes 8x16 always compiled into the text-font backend so we
always have a working implementation even though no modules might be
loaded.

We need the git-revision for module-version checks so provide the

The shl-register module is used to create registries of named-objects. The
main purpose for it will be for module-systems were we have different
backends implementing an interface. The registry can then be used to find
a specific module (or the default module).
No sophisticated filter/search mechanism is used as this cannot be done
efficiently in a generic way.

The standard OpenGL surfaces are y-inverted (which we didn't implement
correctly previously when using our own gbm-surfaces). Therefore, we need
to flip the y-coordinates now as we use correct GL surfaces with the new

Until now we always created our buffers via gbm_bo_create() and used
surfaceless EGL contexts so we can schedule buffer-flips manually.
However, recent gbm and EGL mesa releases include gbm-surfaces that allow
us to ignore all this an let EGL manage the buffers.
This introduces some problems as we are no longer under control of the
buffers so we cannot know which buffer is active. That means, applications
that use the uterm-drm devices must redraw the screen on each frame.

The wcwidth() POSIX helper returns the number of cells that a character
occupies. This is normally 1, however, if it is 0 we simply discard this
input (this should never happen as all characters that wcwidth() returns 0
for should already be handled by the VTE layer).
But if it is >1, we write the character in the first cell, set the width
correctly and mark all following characters as width=0.
Everything else is left unchanged, that means, the running application has
to be aware of wcwidth() and correctly send two backspaces to clear a
width=2 character and so on.
This behavior almost exactly matches the xterm behavior. There are some
corner cases like erasing only one part of a multi-cell character etc.
that might differ. However, these are non-standard cases that no
application should never rely on.
Anyway, if we spot any of these differences between xterm and kmscon, we
should fix kmscon to behave like xterm does.
Thanks to Shixin for looking this up in other emulators.

wcwidth() is a POSIX function that returns the number of cells that a
wide-character occupies. The glibc function cannot be used as it depends
on the locale and we need _always_ UTF8 no matter what the locale is.
This implementation is provided by Markus Kuhn and is equivalent to
xterm's behavior.
