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

This adds a new option to force a global PPI for all fonts. This overrides
per monitor PPI values.
This is useful if monitors do not provide correct PPI values and we want
the same behavior as all other X11 apps (which is 96 PPI forced).
Internally we speak of "Pixels per Inch" as this is more correct. However,
to not confuse users we use the more common term "Dots per Inch".
This also changes the default PPI value from 72 to 96. 96 is the de-facto
default value on linux so we should use it, too.

We need a copy of xkbcommon-keysyms.h as long as xkbcommon is not included
in all major distributions. We _need_ this build-time dependency,
otherwise, we cannot build the other keyboard backends.
However, requiring xkbcommon as build-time dependency is not a solution as
no major distribution includes it.

Remove the last reference to uterm structures so we can put the vte layer

If the CPU is too slow to render the console in a decent speed and we have
to skip frames, then we should print warnings if debug mode is on.

This option allows changing the console renderer during runtime. This is

Instead of redrawing on change, we now use a framerate-timer which
redraws the screen. This timer stays active for 1s after the last redraw
so we do not enable/disable the timer while the console is under heavy
work-load. This still needs to be benchmarked but it seems to work nicely.

Similar to the UI subsystem, we also need to be aware of our current state
inside of the terminal subsystem. We can now avoid rendering graphics when
not awake. This suppresses odd warnings that occured when keeping an
application active and printing in the terminal while the terminal was in
background.

We used to have a global video object for each terminal. However, this has

Move display-removal from terinal subsystem to UI subsystem to avoid

This new function allows external subsystems to remove displays from the
terminal objects. It is required to make the terminal subsystem
independent of the uterm-video subsystem to allow different displays from
different video-objects to be part of a terminal.

The drm video backend does automatically blit the framebuffer on wake-up,

If OpenGL is not supported, we now allow 2D blitting into the video
