* Manually merged 9090cda92ce3a119ad3b5aad491b8545a87fa103 by mvwieringen * "Make fastlzlib.h usable for C++" [as zlib.h is]
* Synchronized LZ4 code to r90 (http://code.google.com/p/lz4/)
* Manually merged 8c4cdb259a0b0f1d4b92f86d80df8e9242d5a505 by mvwieringen * "The zlib deflateResetKeep that is called from deflateReset of which fastlzlibReset is an equivalence off resets more fields so added resetting these fields in fastlzlibReset too"
* Removed unused zlibLevelToFastlz()
* Use real zlib compression levels At level Z_BEST_COMPRESSION, LZ4 backend uses LZ4_compressHC() (lz4HC with high performance decompression) The fastLZ backend is now optional
* Build cleanup.
* Moved LZ4 and FastLZ code in subfolders so that the build is not too messy.
