It allows to add callback called before/after a picture is used.

Currently, detection is done at build time. Feel free to add run-time
detect if you know how.

While VFP/NEON do support floating point instructions, they appear to
be noticeably slower than fixed point.

alloca() was not used anyway on OSX and BSD, due to smaller stack sizes,
and we can't assume a default stack size anyway

I expect the performance loss to be minimal, but worth the code
simplification anyway (i didn't benchmark)

aout_BufferAlloc() is moved into its own function in a .c file instead
of being a macro

Since there is now 2 types of allocations (HEAP and NONE), make
i_alloc_type a boolean (true = HEAP alloc, false = NO alloc)

make aout_BufferFree() a static inline function in the same process.
Prototype doesn't change since the provided buffer doesn't need to be
set to NULL (I checked all the callers)

There is a bug in AStreamSeekStream that is causing all input modules
that support CAN_SEEK to be treated as CAN_FASTSEEK.  This in turn
causes far too many seeks in slower seeking sources which results in
performance problems when playing video.  The fix is a simple change of
CAN_SEEK to CAN_FASTSEEK.

 It's not perfect, as they do not have the same dynamic, but it costs a lot
of CPU for something not that visible.
 If an option is wanted, it is easy to add.

is found (same function but not same data).
This can be usefull to find some errors.
This is only activated in debug mode.

 * Shrink the buffer in either direction before reallocating,
   so we don't need to copy discarded data.
(* Special case if the payload is entirely discarded.)
 * Avoid potentially overflowing pointer comparisons
  (In real life, it works, but it is not defined by the C specification).
