Cleanup and refactor our atomic library.
This commit: * Removes most of all dirty internal details from public atomi_ops.h file, and move them into /intern private subdir. * Removes unused 'architectures' (__apple__ and jemalloc). * Split each implementation into its own file. * Makes use of C99's limits.h system header to determine pointer and int size, instead of using fix hardcoded list of architectures. * Introduces new 'faked' atomics ops for floats. Note that we may add a lot more real and 'faked' atomic operations over integers and floats (multiplication, division, bitshift, bitwise booleans, etc.), as needs arise.
