Add a buffer overflow check in RLE encoder.
Avoid calling RLE encoding if extra data length is zero.
Make 2KB block size default for non-global deduplication.
Update test cases for new 2KB block size support.
Avoid using fingerprints in minhash computation and fix write amplification
Modify min-heap to use 64bit values
Improve bsdiff performance
Fix pointer comparison in bsdiff
Use 32bit offsets in bsdiff to reduce memory usage
Improve Zero RLE Encoder performance
Add more buffer overflow checks in Zero RLE Decoder
Avoid different optimization flags for Dedupe sources.
Fix liberal mixing of uint64_t and int64_t (should all be uint64_t).
Fix corner case crash when decompressing.
Fix latent bug when calling algo deinit in decompression code
Reduce diff threshold for slightly greater delta encoding
