Log Message:
Changes 0.9.7:
 * Yet more large file support fixes.
 * C++ support for easy #include <librsync.h> in C++.
 * Removed Debian files from dist tarball.
 * Changed rdiff to an installed program on "make install".
 * Refactored delta calculation code to be cleaner and faster.
 * #879763: Fixed mdfour to work on little-endian machines which don't
   like unaligned word access.  This should make librsync work on
   pa-risc, and it makes it slightly faster on ia64.
 * #1022764: Fix corrupted encoding of some COPY commands in large
   files.
 * #1024881: Print long integers directly, rather than via casts to
   double.
 * Fix printf formats for size_t: both the format and the argument
   should be cast to long.
