netlist: memory management. [Couriersud]
Memory management in plib is now alignment-aware. All allocations respect c++11 alignas. Selected classes like parray and aligned_vector also provide hints (__builtin_assume_aligned) to g++ and clang. The alignment optimizations have little impact on the current use cases. They only become effective on bigger data processing. What has a measurable impact is memory pooling. This speeds up netlist games like breakout and pong by about 5%. Tested with linux, macosx and windows cross builds. All features are disabled since I can not rule out they may temporarily break more exotic builds.
