bitset: rename confusing macro NAND to ANDNOT 

s/BIT_NAND/BIT_ANDNOT/, and for CPU and DOMAINSET too.  The actual
implementation is "and not" (or "but not"), i.e. A but not B.
Fortunately this does appear to be what all existing callers want.

Don't supply a NAND (not (A and B)) operation at this time.
