Char: ip2, macros cleanup

- remove i2os.h -- there was only macro to macro renaming or useless
  stuff
- remove another uselless stuf (NULLFUNC, NULLPTR, YES, NO)
- use outb/inb directly
- use locking functions directly
- don't define another ROUNDUP, use roundup(x, 2) instead
- some comments and whitespace cleanup
- remove some commented crap
- prepend the rest by I2 prefix to not collide with rest of the world
  like in following output (pointed out by akpm)
