Typedef removal tool

[Luis R. Rodriguez]

Anyone know if there is a typedef removal tool? When porting drivers
this needs to be done quite often.

FWIW I've started porting some driver and have come across some tools,
or written my own scripts, which have helped. Using spatch to port a
driver was such a tool I explored. I think I'll try to put together
some info on the driver project wiki for this. typdef removal tool
would still be neat.
