Remove gSystemHeap and use _buffersSegmentEnd instead, make buffer alignments explicit for gcc (#1901)
* Remove gSystemHeap and use _buffersSegmentEnd instead, make buffer alignments explicit for gcc * ALIGNEDn -> ALIGNED(n), reposition alignment attribute for PreNmiBuff * Correct positioning of ALIGNED for filter data in audio/lib/data.c * Add ALIGNED to TypenameMacros * ALIGNED(4) on same line for PreNmiBuff * Revert audio load.c change, to be submitted separately
