Extensive changes to APIs to allow use of a nominated value to mask
against (the maskVal). Previously, the mask values were either
hard-coded (e.g., PM_MASK_SAT) or taken as anything non-zero. The
code is tested under psphot (which has similar changes) and does not
crash, but neither is it successful in marking all bad pixels (EAM
will investigate). For this reason, I have left the "gutter" pixels
(cell gaps) set to 0 instead of NAN in pmFPAMosaic.
