47a3c4f5b5 stb_vorbis.c - Detect __NEWLIB__ for alloca.h 
This is needed for `stb_vorbis.c` to compile for the Wii U using
devkitPro.

This should theoretically also fix compilation for the Nintendo
Switch, 3DS, and Wii (with devkitPro, that is) as they all also use
Newlib.

Newlib is also used by Cygwin:
https://cygwin.com/git/?p=newlib-cygwin.git;a=blob;f=newlib/libc/include/alloca.h;h=5d36318914282280b353aed457e1b1f64947b584;hb=HEAD

And the Google Native Client:
https://chromium.googlesource.com/native_client/nacl-newlib/+/refs/heads/master/newlib/libc/include/alloca.h

As you can see from these links, these both provide `alloca.h` as
well, so it appears to be a safe guarantee that `alloca.h` is
available on Newlib.

Added debugging check on line 1604 
I added the code assert(f->valid_bits >= n);  instead of removing if (f->valid_bits < 0) return 0; to improve code with checking and debugging instead.

Remove if (f->valid_bits < 0) return 0; on line 1603 
I propose to remove this line because  f->valid_bits will never be less than zero since, in the while loop, you're adding 8 to it. Therefore, it will always evaluate to false. This is to help remove redundant code.

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.

Fixes #842.

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).
