The Check test framework forks by default which is annoying when running gdb.
Try to detect whether we're inside gdb by ptracing ourselves. If that works,
we're not inside a debugger. If it doesn't, then assume we're inside a
debugger and set CK_FORK to "no".

doxygen doesn't detect enum cross-references automatically, prefix them with
@ref

doxygen actually copies that over into the resulting output.

Some devices (PS3 sixaxis controller) merely have a bunch of axes, without the
semantic information that linux/input.h requires. For those, the ABS_MT range
may be merely another axis, not the special range that we need to treat it
with.

Use a simple heuristic: if ABS_MT_SLOT - 1 is enabled, don't treat ABS_MT as
multitouch axes. The ABS_MT_SLOT - 1 axis is not used for a real axis.

All clients that want to handle SYN_DROPPED correctly need to pass an EV_SYN
through their own handlers before starting with the syn events. Rather than
letting them synthesize that, guarantee that the event is defined the first
time LIBEVDEV_READ_STATUS_SYNC is returned.

This does not change existing behavior, it merely documents it so we can rely
on it.

We shouldn't have a separate API for that, the whole point of libevdev is to
abstract the quirkyness of the ioctls into a common interface. So let's
export the two EV_REP values through libevdev_get_event_value.
