- PM: used GetCountMifare in MifareNested() for improved timing accuracy and to deliver better quality nonces - PM: MifareNested now delivers exactly two different nonces to avoid time consuming multiple lfsr_recovery32() on client side - Client: replaced quicksort by bucketsort in crapto1.c which is faster - Client: use multithreading (two parallel calls to lfsr_recovery32()) - Client: fixed a small bug in mfnested() (always showed trgkey=0) - Client: introduced a mutex for PrintAndLog() to avoid interlaced printing Minor rework of hf mf chk: - Avoid time consuming off/on cycles. Send a "halt" instead.
