Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for
GIF they can be considered better than bayer (provides more gray-levels), and
spatial stability - often more than twice as good compression and less visual
flicker than error diffusion methods (the methods also avoids error-shadow
artifacts of diffusion dithers).
These methods are similar to blue/green noise type dither masks; but are
simple enough to generate their mask on the fly. They are still research work
in progress; though more expensive to generate masks (which can be used in a
LUT) like 'void and cluster' and similar methods will yield superior results
Improves rgb -> gray16 conversion
Fixes Ticket3422
The pam and png output files look visually similar, in both cases the
dynamics increase to 0x0 -> 0xfffb.

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
Aligning the tables reduces the amount of code generated on
e.g. ARM as the offset constant then has few enough set bits
so it can be encoded inside a single instruction instead of 2.
Ideally all should be declared aligned, but the DECLARE_ALIGNED
macros does not work with pointer tables, thus also reordered
the tables.

This reverts parts of d6d5ef5534, that didn't work right. (The
tests that were added failed on big endian, and the output looked
garbled on little endian as well.)
This is due to the fact that the intermediate scaling values (from
e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and
thus requires a separate output function, while yuv2gbrp_full_X_c
only interprets it as int16_t.

This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.
