If e.g. an 18 x 11 PNG image used 1 bit depth and a single component
the source data fed to fz_unpack_tile() would have padding bits at the
end of each line of whole bytes, because 18 bits is not a multiple of 8.
The optimized 1 component versions of fz_unpack_tile() for a bit depth
of 1 deliberately read the padding when doing the table lookups, knowing
that this does not matter because of the construction of the table.
Valgrind is incapable of understanding this, so we provide some extra
masking (used only in PACIFY_VALGRIND builds) that explicitly mask
off the invalid bits.

This avoids us having to check the entire array each time, and
makes the next commit simpler.

This is useful when a TIFF image is grayscale but
supplies more than a single component per sample.

This silences the many warnings we get when building for x64
in windows.
This does not address any of the warnings we get in thirdparty
libraries - in particular harfbuzz. These look (at a quick
glance) harmless though.

When no alpha present, we were omitting to decode the last
component.

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.

In general, we should use 'const fz_blah' in device calls whenever
the callee should not alter the fz_blah.
Push this through. This shows up various places where we fz_keep
and fz_drop these const things.
I've updated the fz_keep and fz_drops with appropriate casts
to remove the consts. We may need to do the union dance to avoid
the consts for some compilers, but will only do that if required.
I think this is nicer overall, even allowing for the const<->no const
problems.

Purge several embedded contexts:
Remove embedded context in fz_output.
Remove embedded context in fz_stream.
Remove embedded context in fz_device.
Remove fz_rebind_stream (since it is no longer necessary).
Remove embedded context in svg_device.
Remove embedded context in XML parser.
Add ctx argument to fz_document functions.
Remove embedded context in fz_document.
Remove embedded context in pdf_document.
Remove embedded context in pdf_obj.
Make fz_page independent of fz_document in the interface.
We shouldn't need to pass the document to all functions handling a page.
If a page is tied to the source document, it's redundant; otherwise it's
just pointless.
Fix reference counting oddity in fz_new_image_from_pixmap.
