The man_fixup_aliases thingy was a horrible hack. Replace it with a
temporary .man_fixup file that saves compilation timestamps so we have
post-recipies for man-fixups.
Also fix some minor out-of-tree build problems.

We need the git-revision for module-version checks so provide the
infrastructure now and print it in log_init().
Note that the git-describe string is distributed with the tarballs so
end-users will not have to generate it themself. But when building from
git, the revision will be automatically updated whenever something
changes.

Instead of implementing a thread-safe backend-system we can now use the
new shl-registry storage module.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
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
drm-uterm backend.

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.

We must pass "-p" to make "login" preserve the environment. We make sure
the environment is correctly reset before calling it so it is safe.
Furthermore, this allows us to pass additional environment variables to

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.

Multi-cell glyphs are glyphs that span across multiple horizontal cells.
The font renderers already support this. This patch fixes the console
renderers to take advantage of this.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
Instead of clipping every character to a one-cell boundary, we now render
multi-cell characters correctly into multiple cells.
This does not adjust the console-renderers but only the font renderers to
provide the correct glyphs.

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.

kmscon does always pass a proper argv array so the default is never used.
However, for security reasons we shouldn't hardcode /bin/login. If some
other program uses the pty layer and forgets to pass in a suitable argv
all the time, they mind end up with opening a root shell.
Hence, use /bin/login as default.

Instead of relying on --switchvt, we should always activate fake-VTs
during startup. Otherwise, we might end up with dead seats as there is no
way to wake up kmscon later.

We tried to avoid running unused code during shutdown by moving VT
handling into a separate eloop and run it exclusively. However, with
delayed VT switching, we need to run other event-handlers to make the VT
switch work. Therefore, run all of this during shutdown and remove the
vt_eloop event-loop.
This means that we might create new seats, displays, etc. during shutdown.
This is valid and doesn't harm kmscon, but we want to avoid doing stuff
that is undone few miliseconds later. Therefore, we set a "exiting" flag
and check that before initiating most of the big handlers.
