Move JFFS2 from the Cygwin implementation of CRC32 to the zlib implementation which can take advantage of hardware acceleration and reduces code duplication. Synthetic benchmarks on AArch64 hardware show approximately a 17x improvement in CRC32 calculation speed and real-world testing with JFFS2 shows a 1% improvement in mount times, a 5% improvement in data write times, and a 9% improvement in garbage collection times. A test was written to compare hash generation between the two algorithms and a partition was created with one and then remounted with the other with no errors.
