This lets libevdev provide a relatively generic interface for the
creation of uinput devices so we don't need to duplicate this across
multiple projects.
Most of this is lifted from the current test implementation, with a
couple of minor changes.
EV_REP needs special handling:
Kernel allows to set the EV_REP bit, it doesn't set REP_* bits (which we
wrap anyway) but it will also set the default values (500, 33).
Device node is guessed based on the sysfs path:
The sysfs path contains a eventN file, that corresponds to our
/dev/input/eventN number. Use it so clients can quickly get the device
node, without a libudev dependency.

This way any ABS_MT_ event value that comes in will also be stored in abs_info.
That always corresponds to "current slot", so if a user calls
libevdev_set_event_value() or libevdev_get_event_value() they're actually
modifying the current slot value.
When the current slot changes, sync the state back into the absinfo values.

This enables libevdev_get_event_value(dev, EV_LED, LED_NUML); to check

Simply enabling the bits is not enough, we need to provide axis

No real effect on the test, this check is just so that a follow-up patch to

Changing a single value on an abs axis is slightly more common than
having to enable that axis outright. Provide a set of accessors for
doing so.
