STB Vorbis: prevent division by zero in decode_resign if ch == 0 
In the call to decode_residue:
  decode_residue(f, residue_buffers, ch, n2, r, do_not_decode);

The channel count is previously intialized as zero and incremented
based on a for-loop (f->channels) plus a conditional,
if (map->chan[j].mux == i).  If this doesn't happen then 'ch'
remains zero.

Once inside decode_residue(..), the code has three branches based
on channel count: stereo (ch == 2), mono (ch == 1), and then the
exception if it's neither of those (simple 'else').  It's in here
where a zero-valued 'ch' can be used as the denominator in these
calculations:
    int c_inter = z % ch
    p_inter = z/ch;

Obviously this 'else' branch is meant for channel counts greater
than two an not for zero channels; so this change simply makes
that branch only valid if (ch > 2).

15516199e5 stb_image_write: Update JPEG code to jo_jpeg 1.60 
For quality <= 90, it now supports subsampling U and V
so it encodes smaller files.

See https://www.jonolick.com/home/jo_jpeg-release-160 for more info

57b9ea6510 Quell -Wcast-align warnings from Clang 
The stbi__sbraw() macro in stb_image_write.h causes Clang to spew about 24
warnings complaining that "cast from 'unsigned char *' to 'int *' increases
required alignment from 1 to 4" when compiled with the -Wcast-align option.

In practice, this is spurious so long as STBIW_MALLOC() and STBIW_REALLOC()
follow the usual alignment semantics for malloc() and realloc() in that they
align sufficiently for any built-in type.

To quell the warning, we can cast through a void pointer as an intermediary.
