Log Message:
Update chmlib to 0.36.  This version includes two security fixes.

Changes:
    - Major security fix (iDEFENSE Security Advisory IDEF1099 - Stack Overflow
      Vulnerability)
    - Major security fix from Palasik Sandor (LZX decompression buffer overrun)
    - Bugfix/enhancement from David Huseby to make the "what" flags to
      chm_enumerate work correctly, and to pass the flags along to the callback
      function (via the chmUnitInfo structure) so that the callback doesn't
      need to re-parse the filename.
    - Compilation fixes for x86-64 from Vitaly V. Bursov.
    - Miscellaneous fixes to the configure script, including some significant
      cleanup by Vadim Zeitlin.  The changes from Vadim should also allow the
      configure script to correctly configure the build on OS X, where it was
      previously failing to note that pread64 doesn't work.
    - Minor update to the Makefile.in to do a mkdir before the install, in case
      the specified INSTALLPREFIX directory is non-existent
