Rearrange pawn moves generation

This patch greatly cleanups generation of pawn moves but
we change the order in which moves are generated so there is
a change in functionality, but not in perft.

The only real functionality change is that now when type == CHECK
we generate knight underpromotion captures only if give check and
not always as before.

Perft is 2% faster and fully verified.
