This was unstable.

We don't need it.

We don't want users to not press this button just because there is an other one afterwards.

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)
