  63. Fix a case where X server audit messages do not get printed (David Dawes).
  62. Initialise the allocator even earlier in the X server startup, and use
      it for the logging functions (David Dawes).
  61. Parser option handling cleanups/fixes:
       - Ensure that option data is allocated by the parser, rather than
         externally allocated or static.
       - Free replaced option data.
       - Make xf86ParseOption's handling of multiple options of the same
         name consistent with all other cases (last occurrence is used).
       - Fix a bug in the handling of the Keyboard section "xleds" keyword.
      (David Dawes).
