e6f85ee1f1 Add two helper functions to check event type/code 
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.

c661e80ba0 Switch to a state machine to handle incomplete syncs 
A caller may start syncing but switch back to normal half-way through the
sync. In that case, we need to drop all sync events and continue with
regular events only.

f3a6b0c685 Add a flag for blocking read 
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.

a10fc33cd8 If the caller doesn't sync when it should, process all events regardless 
libevdev needs to maintain the correct state of the device, even if the caller
decides to drop all delta events after a SYN_DROPPED.

fe30bf7d96 Drop code for kernel-enabling bits 
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.

we have a problem. Log that so that the process can print a warning.

bc285acd9a Add a flag for forcing a SYN_DROPPED event 
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.

dc27c627a7 Fix type_to_mask to return -1

returning 0 on failure is a bad idea, as mask is unset.
