Changes since version 3.0q:
===========================
Xdelta-3.0u release notes:
* New xdelta3 merge command (issue 36)
* Windows stdin/stdout-related fixes (issue 34)
* Fix API-only infinite loop (issue 70)
* Various portability and build fixes (gcc4, DJGPP, MinGW, Big-endian,
Solaris, C++)
* New regression test (yeah!)
Xdelta-3.0t release notes:
* Improves compression by avoiding inefficient small copies (e.g.,
copies of length 4 at a distance >= 2^14 are skipped)
* Fixes an uninitialized array element in -S djw which did not cause
a crash, but caused less than ideal compression and test failures
* Fixes bugs in xdelta3 recode, tests added
* All tests pass under Valgrind
Xdelta-3.0s release notes:
* Faster! Several optimizations to avoid unnecessary arithmetic
* xdelta3 -1 has faster/poorer compression (xdelta3 -2 is the former
configuration)
* -S djw exposes secondary compression levels as -S djw1 .. -S djw9
* Removes "source file too large for external decompression" error check
* API support for transcoding other formats into VCDIFF
Xdelta-3.0r release notes:
* Fixes an encoder crash caused by -S djw (secondary compressor) on
certain data, new tests for code-length overflow
* Adds new recode command for re-encoding a delta with different
secondary compression settings
* Fixes API-specific bugs related to non-blocking calls to
xd3_encode_input and xd3_decode_input
* Adds new examples/encoder_decoder_test.c program for the non-blocking API
compatible with 1.x so it gets it's own package. Based on patch from "BK"
received in PR 36191.

Given two binary files, create a compressed binary diff of them. Also
provides the ability to patch the diff back to the original file to create
the new file.
