8f2a153dc2 STB Vorbis: eliminate inaccessible branch 
The eliminated code removes the (ch == 1) branch, which is scoped
within this if condition: `if (rtype == 2 && ch != 1)`, therefore
the (ch == 1) branch will never be taken.

a7a899fdb0 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).

d2333979cf Tailor SDL_Sound for interal use by DOSBox 
- Removes extraneous (and unused) includes

 - Cleans up many compiler warnings

 - Fixes SDL include statements (using proper `#include <file.h>` directives
   given the prior `#include "file.h"` directives should only be used when
   including a projects' own header files instead of -Ipath-provided system
   headers)

 - Eliminates extraneous codecs

Many of these were made after building SDL_Sound under various compilers
and operating systems and hitting various issues. It currently builds
clean without errors or warnings on all our workflow compilers and
versions.
