- Fix byte-reading in the decode function by using a guint8, instead
of an int, we were overreading and were getting keycodes of
0xffffff44 when we wanted a single byte of 0x44.
- Remove use of KEY_REMOTE_X, those keys never got upstream, and the
values they were defined at are now used for completely different
keys
- Update uinput.h with the latest keycodes from 2.6.27

Cheers
