Uses stack instead of allocating stuff haphazardly (16 bytes and 512 bytes respectively) - removes malloc() pollution and all that nasty stuff from tight loops
Original work by Ribbit but edited by me.
Will NOT bring a massive speedup since the main bottleneck is mbedtls itself, but may bring nice oddities to STARTUP TIMES nonetheless.
AES instructions being forced wont affect CPUs without them since there is always a runtime check for them.
