As a refinement to the KILLT code, I noticed that the KILLT tables
for both white and black is exactly the same (see Initialize_killt()
in init.c).  As the killt tables are always restored after a move
generation, then there is no need to have different tables for both
white and black, i.e. they can use the same tables.

Hence in genmoves.c, there is no need to perform any of the [mv | sidebit]
operations.  We should be able to remove the sidebit variable safely.
