[PATCH libevdev 1/3] Add a more consistent naming scheme

[Peter Hutterer]

After porting evemu to use libevdev as backend I found a few inconsistencies
with the current function names. These patches rename a bunch of the setters
to be more predictable.

Old functions are kept for now, just in case someone has already started
porting something to libevdev. The deprecated functions will be removed
with libevev 0.4.

Cheers,
  Peter
