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
is better and easier to maintain.

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
code.

Callbacks looked good on paper, but synaptics ran into an issue already that
it just couldn't easily pass around the state needed in the actual event
processing function.
Replace with a new interface that only returns the next event (still reading
more off the fd while doing so).

Two main goals of this library:
- 'transparently' handle SYN_DROPPED events
- avoid errors in ioctl handling by providing a simpler interface.
Keeps a cached copy of the device for quick querying.
