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.

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.

Just enabling EV_REP sets them to zero, but when enabling them directly,
a value is required.

Except for the API documentation, that'll stay on github for now until
I figure out where to put it (and have the space to put it in).

These aren't really that useful since they're just one or two lines in
code, but it saves callers from accidentally misplacing braces, etc.

Not all clients need nonblocking read, so add a flag to read
in blocking mode. In that mode, events are only read from the fd when
the queue is empty.

We can't enable axes on devices at runtime in the kernel, not even
for uinput devices. So this API can't work anyway, remove it before
someone thinks it does work.

uinput doesn't route a SYN_DROPPED, so we neeed to handle fds in
a rather complicated manner. For tests, avoid this and instead force
the library to sync if a specific flag is given.

Doxygen is bad for man pages, but having an online API documentation

Enum values fo 3 and 4 to avoid callers using true/false values for grabbing
and ungrabbing. If the evdev mute ioctl is merged, we can extend this
without having to worry about breaking callers.

libevdev_new() can only fail on allocation failures, but with an fd the
failure options are more. Split into a new function that can return an error
