xkbcommon supports reporting multiple keysyms per key-event. There is no
keymap which uses this, yet. However, this feature is not meant to enhance
performance by reducing the number of calls into xkb, but instead multiple
keysyms are to be handled as one big keysym.
But there are no examples, yet, so we cannot actually perform any
conversions on them. But we can add the infrastructure for it.

This changes the uterm-input infrastructure to use XKB directly instead of
using a modularized infrastructure. There is no need to use something else
anymore.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
We made xkbcommon mandatory some time ago and there is no reason to keep
this plain backend around anymore. It isn't tested at all and provides no
real advantage over xkb.
Even for debugging it is easier to use XKB.

If multiple handlers are called on the same input-event, we must notify
handlers whether the event was already handled by a previous callback. We
push this decision to the handlers by allowing them to modify the
"handled" flag for an input event.

AM_PROG_AR is a new feature since autoconf 1.12.
autogen.sh failed on Ubuntu 11.10 without this patch with:
configure.ac:30: error: possibly undefined macro: AM_PROG_AR
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
AM_PROG_AR is required only for autoconf-1.12 so we can just skip it if
using an autoconf version that does not include it.

When adding new elements, we should add them at the tail, not at the
front. And when removing elements, we should remove them from the tail,
too.
We also convert the whole stuff to the shl_dlist API so we do not have to
manage the linked-list ourself.
Note that this silently breaks the idea of having multiple listeners with
the same function+data in the hook. This is because removing the listener
may now change order of two identical entries, as we don't know which of
them to remove. That means, when adding two identical entries, you cannot
rely on them to retain their position in regard to each other.

We now set KBMODE to K_OFF so we are totally independent of kernel input.
Instead, we handle VT switches with uterm-input now. This also allows us
to have full control of which keyboard input is parsed by us and which is
parsed by the kernel.
We still need to set a flag for uterm-input events that they were handled
to avoid having the TSM layer handle these events again.

This modifies the generic VT layer to register input-cbs for all VT types
and dispatch the event to the correct handler.
This will allow us to handle VT-switches for real VTs ourself instead of
relying on VT input.

This whole concept was broken from the beginning. With hotkey based
activation we have a much better debugging tool. This is still very
fragile, but better than nothing. And we are doing pretty well in error
recovery during hijacked VT switches so that's not as problematic as one
might think.

Recent systemd was updated to parse XDG_SEAT in PAM so we can assign
logins to the correct seat.
This patch allows pty users to specify what seat they run on so the PTY
can correctly set the seat variable. If no seat is specified, then
XDG_SEAT is not set so we still allow non-seated logins.
Note that if kmscon_pty is run with XDG_SEAT set, this will also be set
for the client PTY so unset it if you don't want the environment to be
copied to the client (like any environment variable).

We need to draw the final character of a selection with inversed

This implements UI selection for the console buffer. This selection is not
to be confused with PTY application selection provided by the
mouse-protocol via VT200 protocol.
Instead, this selection allows UIs to tell the TSM layer to select a
special part of the screen. Moreover, it allows selections to go into the
scrollback-buffer and to be bigger than a single screen. The UI can even
implement scrolling during selection to allow arbitrarily big selections.
There might still be some special cases where we need to fix selection.
However, it already works pretty well.

If we have pointers somewhere into the scrollback-buffer, there is not
easy way to see which of two lines comes first. Therefore, we introduce
scrollback buffer IDs. These are unique and every line gets one assigned
when it is linked into the sb-buffer. These IDs guarantee that front lines
have lower IDs than bottom lines.

This function is not used and I do not intend to use it anywhere soon.
Therefore, remove it so it doesn't generate sparse warnings.
The only reason why I kept is was that we might want to retrieve these

near future as we need to keep a buffer-fill state for it.
