Jiri Slaby 7b19ada2ed get rid of input BIT* duplicate defines
get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)
