Rename the C functions bitand(), bitor() to bit_and(), bit_or().

This is to avoid use of the C++ keywords "bitand" and "bitor" in
the header file utils/varbit.h.  Note the functions' SQL-level
names are not changed, only their C-level names.

In passing, make some comments in varbit.c conform to project-standard
layout.
