All terminal-emulation code is moved into a new library called "TSM -
Terminal State Machine". So we rename everything to have a separate
namespace.

Instead of requiring to use uterm_screen objects we now add a
fake_blendv() request directly to the display object. We rename it to
"fake_blend" instead of just "blend" so we can later implement real
blending.
This reuses the existing infrastructure. But the fake_blendv is the way to
go so we rename the existing functions to "fake_*" either.

Instead of requiring to use a uterm_screen object we now also add these
helpers to the display directly. This allows to use libuterm without any
screens, which is often useful if no virtual screen are needed.

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.

libkms doesn't link to libdrm so our current check for gbm_bo_get_stride()

pre-cbs are similar to post-cbs but they are called _before_ the actual

Instead of using an ev_counter object internally, we now directly create a

When integrating other event-sources or event-loops into eloop which do
not provide FD-abstractions, we often want to check for specific
conditions before returning from the dispatch-callback or going to sleep.
Therefore, you can now register a post-dispatch-cb and check whether your
alien event source is firing. If it is, simply push an idle-source into
the event-loop and it will fire during the next dispatch without going to
sleep.

This new helper allows retrieving a single file descriptor which
represents the whole event loop. This is very useful if you want to use

"10" is really small and not really suited as default value. We currently

We need to know whether a current attribute was created with a specific
RGB value or whether a vt-color-code was used. This is, because several
affects have to be applied when color-codes are used. For instance, bold
colors are always brightened to simulate "bold".
Therefore, two new fields are added which contain the color-code or -1 if
an RGB value is used. All of this is always applied internally of the VTE
layer so other layers (like the console layer) can be sure, that the RGB
value is always correct and use it.
But the VTE layer needs to keep track of the color-codes so we put them
into the attribute structure.

This removes this legacy name and also moves the attribute structure into

BCE is implemented by all major terminal emulators and activated by
default. If used, then every erase/insert/scroll/delete operation will
redraw the background of the erased/new characters with the current
background color instead of the default background color.
There is currently no way to control this behavior from an application so
you cannot turn it off. However, every terminfo based application can read
whether it is activated from the terminfo database.

We still depend on xproto during compile time as we need the keysym
definitions. We could simply copy the keysym file but I really want to
wait until xkbcommon is finally released as it includes a keysym header,
too. Then we can simply depend on xkbcommon during build.
However, as we still need a way to perform the other conversion: string to
keysym, we need some hashtable anyway. So we can then also copy the keysym
definitions, too.
