When the kernel inserts a repeat frame it does that with EV_KEY code
value of 2 and the frame itself is a SYN_REPORT with value 1. Nothing in
libinput wants those repeat values, so let's discard them here before
anything tries to process them.
This inserted frame causes bugs on touchpads with EV_REP (rare enough)
because while the key event itself is dropped, the timestamp of the
frame still causes the next real frame's delta time to shorten,
resulting in wrong acceleration values.
Closes#1149

mtdev is used only for MT Protocol A device of which there are quite
few. But that protocol is also a perfect example for event frames in ->
different event frame out so let's move this into the plugin pipeline.
Because the plugin doesn't really have full access to the device's
internals we set up mtdev base on the libevdev information rather than
just handing it the fd and letting it extract the right info.
A minor functionality change: previously mtdev-backed devices returned
zero on libinput_device_touch_get_touch_count(). Now it is hardcoded to
10 - the number of callers that care about this is likely near zero.
Because it's now neatly factored out into a plugin we can also make
mtdev no longer a strict requirement.

No functional changes, all the actual interfaces now simply loop through
the frame instead of expecting the dispatcher to do so.
The mtdev code changed slightly since we can shortcut in the non-mtdev
case.

Touchpad devices are pointers too in libinput but they don't usually
have wheels. Let's check for REL_WHEEL in device_new *and* then again
for the actual pointer capability in device_added.

The function name doesn't represent what the function really does.
Rename it and be consistent with the naming of other related functions
like wheel_set_scroll_timer() or wheel_cancel_scroll_timer().

The custom implementation of the send-events mode for tablet pads does
not actually suspend and resume the device, so events continue to be
sent despite the device being theoretically disabled. Fix this by
removing the custom send-events implementation in favor of
evdev_dispatch's implementation.
Also add a simple test to ensure the send-events mode works.

The vast majority of plugins are only interested in a single or a few
devices. Require that they enable the frame callback for those devices
and don't notify them for any other frames.
Give each plugin a unique index and use that for a bitmask to check if
the plugin wants events for a particular device. If not, skip it.

If the button we want to map to isn't enabled by the kernel allow
setting the button nonetheless. On some tablets we only get the
actual number of button codes (e.g. BTN_STYLUS only on an Inspiroy 2S)
so not being able to map the eraser button to some other button makes
this whole feature a bit pointless.
Special-case BTN_STYLUS* because these are the ones we'll always allow.
This fixes an issue with the eraser button defaulting to BTN_STYLUS2
on some devices but it couldn't actually be set to that value by the
caller.

This adds the public API to configure an eraser button on a tablet tool
to emulate a normal button. In DEFAULT mode the eraser button will
simply do whatever it does by default (i.e. toggle to eraser).
In BUTTON mode the eraser button will be converted to a regular tool
button event, with libinput handling the underlying proximity event
madness.
