In commit 85b1c5345b, I introduced a new "max_len" variable, used by the
search() function to store the maximum match length found in course of
the binary search.
However, I overlooked the fact that the search() function then lost
thread safety, as "max_len" would be shared by all threads of a process
using libbsdiff.
Fix the issue by not using a global variable, instead updating "max_len"
via another pointer, just like the "pos" variable is handled already.

This project is a forked version of BSDiff, as taken from the Chromium project at SVN Revision 122769. See README.chromium for background on its origins. Significant changes after the fork include: - Changing the BSDiff file format to support file owner, group, and permission information. - Adding more robust error handling. - Adding a new program, bsdump, that outputs BSDiff header information. - Converting the core functionality into a library, libbsdiff, with public API functions make_bsdiff_delta() and apply_bsdiff_delta().
