fz_pixmap revamp: add stride and make alpha optional
fz_pixmaps now have an explicit stride value. By default no change
from before, but code all copes with extra gaps at the end of the
line.
The alpha data in fz_pixmaps is no longer compulsory.
mudraw: use rgb not rgba (ppmraw), cmyk not cmyka (pkmraw).
Update halftone code to not expect alpha plane.
Update PNG writing to cope with alpha less input.
Also hide repeated params within the png output context.
ARM code needs updating.
