Remove useless razoring condition

Condition is always true! For any value of the
array index! Even an out of bound array, like
razor_margin[120]!!!!

No functional change.

Rename shift_bb() to shift()

Rename shift_bb() to shift(), and DELTA_S to SOUTH, etc.
to improve code readability, especially in evaluate.cpp
when they are used together:

old b = shift_bb<DELTA_S>(pos.pieces(PAWN))
new b = shift<SOUTH>(pos.pieces(PAWN))

While there fix some small code style issues.

No functional change.
