commit 6825e71f24cd3f80f065ebcb42de337cd284ec92
Author: Matthew Dillon <dillon@apollo.backplane.com>

    Boot loader fixes - fix recursive malloc()/free() errors, NULL freed fields
    
    * Fix reported loader panics related to corrupt malloc areas.  The zip/gzip
      modules were using a static variable to hold malloc()ed space.  The
      field was getting tromped by recursion.
    
    * Fix numerous cases where file structure fields are not NULL'd out upon
      release.
    
    * Fix numerous cases where a double close might result in a double free.
    
    * Fix a benign bug in libstand's realloc().
