There is a an out-of-bounds access in digi_mixer_start_sound() when
soundnum is < 0. The bounds check I added here is already present in
digi_audio_start_sound().
This bug was triggered on the RPi d2x built when trying to show the
briefing screen because briefing_new_screen() tries to play
SOUND_BRIEFING_HUM, which digi_xlat_sound() translated to -1 in this
situation. The game finally crashed in mixdigi_convert_sound() because
GameSounds[-1] happened to contain some non-zero data (on my Linux desktop,
that memory seems to be always 0 by accident...). This was also the reason
why the pi version tried to allocate lots of memory before it crashed in
memcpy().
Kp already incorporated some small changes I made in my rpi branch into
unification/master. However, besides making the rpi helper functions
static as I did, he also changed the prototype from (void) parameters
to C++ style (). I've incorporated his version here.

Rebirth builds with -Werror=redundant-decls -Werror=undef, which are
triggered by the bcm_host.h. Making gcc treat those paths as
system headers avoids these issues. This was suggested by Kp.
Mac OS X defines uint_fast32_t to unsigned int, causing ambiguous
overloads between RAIIdmem::operator[](std::size_t) and
RAIIdmem::operator[](int). Adding a disambiguating overload for OS X
breaks Windows. Remove operator pointer and operator[]. Rely on the
inherited operator[] for indexing. Require users to call ->get() to
convert to a simple pointer.

Modifying a by-value temporary does not affect the underlying container,
so modifying it is almost always a bug. Require use of a by-reference
capture when modification is desired.

Build function tables at compile time. If !SDLMIXER, compile out the
pointer indirections. If SDLMIXER && PIE, keep function pointers in
read-only memory.
