We want to avoid any static files that are shared between multiple
programs but are not part of SHL. These make the build-process just more
complex.
Move log.[ch] to SHL so we have a known context.

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
helpers.

When text-ops are registered via modules, we need an owner field so
they're correctly tracked. Hence, add this field to all text-ops and
correctly keep module references.

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.

Instead of using the uterm-screen indirection, we now directly access
uterm-display objects. We do not really intend to use virtual screens with
kmscon so there is no need to make this more complex.
I don't think consoles should every provide this feature. Instead, you
should use real compositors for such tasks like Wayland+wlterm. kmscon,
however, is rather an emergency tool or a safe backup than a fancy
daily-use-console.

This is part of the TSM library creation. We also rename "console" to
"screen" as this layer actually manages the screen.

Instead of converting symbols into UCS4 string in each backend, we now
pass the whole data from the console layer into the renderers.
This makes all renderers indepedent of any recently introduced
symbol-tables and they can be implemented inside of TSM without exporting
them. However, we still need to pass the IDs to the text layer. The text
layer must not use them for anything but identification. Moreover, it must
never assume that they are valid tsm_symbol_t values.
We do this so the backends can still have fast hashtable lookups rather
than allocating big keys containing the UCS4 string+length and using these
for lookups.

This moves the timers to SHL and removes the old static_misc header and
source. They are no longer needed.

This removes this legacy name and also moves the attribute structure into
the console subsystem where it belongs. This currently creates circular
dependencies between text and console layers but we can ignore that for
now and fix it later.

The bbulk renderer is very similar to the bblit renderer but it assembles
a request-buffer of all characters and then pushes these requests via a
vector-call to the video hardware.
This turns out to increase performance slightly as we do not call into the
video subsystem for every characters but only once.
This renderer can reduce performance when used with partial-redraws (which
are not implemented, yet), so we keep the bblit renderer around.
