Instead if implementing complex idle sources we now provide a hook so
other subsystems can register callbacks.
This simplifies the code a lot and doesn't drop any major functionality.

Similar to other event sources we now initialize internal data on timer
creation instead of when the source is added to the loop.

When creating a new fd-source you must supply the file descriptor
directly. You cannot delay this to the time when you add the fd to the
event loop.
This simplifies the logic and allows much smoother handling in the event
loop core.

Counter sources are based on the eventfd syscall of linux. Internally, is
uses a 64bit counter which is initialized to 0 and can be increased by the
caller. Whenever the value is non-zero, the fd is marked readable and we
call our callback. We read the 64bit integer (which resets it to 0) and
pass the current value to the callback.
This can be used to implement cross-process notification methods or to
have idle-sources as valid file-descriptors in an epoll set which could be
exported to other applications that are not compliant to our event loop.

Use new uterm_video constructor. This requires hard-coding the DRM card
but this is needed until we use the uterm_monitor interface.

We are actually not interested in the main input device but rather in the
evdev interface. However, the evdev interface is a child of the input
device and therefore has no seat values specifies. This patch removes the
scan-filter for seat tags and performs seat matching in user-space by
first finding the parent of the input device.

We currently only scan devices in uterm_monitor_scan() but we should read
the initial seat values before even searching for devices.

Be more verbose about added and removed devices. Otherwise, debugging is

Internally, we use a new kbd API to handle keyboard related stuff in
uterm. It is a reimplementation of the old kbd_dumb.c backend.

This is a rewrite of the input layer but integrated into uterm. It has the
same functionality but is tightly bound to the concepts behind uterm and
will soon supercede the old implementation.

To allow moving all input handling to uterm, too, we need to detect input

To introduce the new uterm-monitor object we need to remove all the udev
handling from uterm_video. To not break "git bisect" we now remove all the
udev code from uterm_video and uterm_video_drm and make kmscon use the
static /dev/dri/card0 interface for now.

Upstream mesa fixed the missing header protection of xf86drmMode.h so we

The new uterm_monitor watches the system for seat-changes and puts all
devices under the correct seat. This allows to run kmscon on multiple
seats in a single process. It now also correctly handles seat-changes,
that is, devices that are reattached to a different seat on runtime.
It is not integrated into the kmscon source, yet, but will soon be.

We may have to use multiple GL contexts if we mix DRM and fbdev devices.
Therefore, we need explicit GL-ctx management.
We now allow to explicitely activate a specific GL context. This means,
the user needs to use the right GL context before he creates textures or
similar.

A shared signal owns an eloop_fd object. This has a reference of its
connected eloop. Therefore, we must free a shared signal to drop a
reference to the connected eloop and cannot postpone this to
eloop-destruction. Otherwise, the eloop will never get destroyed.

Move to new list-implementation instead of the single-linked list. This

This adds a generic double-linked list implementation so we don't have to
write all list-handling over and over again.
The list-type is similar to the kernel list where we use the same type for
heads and entries. This is a _very_ convenient list-type so we copy it.

The new eloop implementation allows to run the eloop for a fixed amount of

The test_include.h header now provides the basic initialization that will
