    Fix potential memory allocation failure crashes in config.c.
    
    * Added required checks to the returned memory allocation pointers to
    prevent crashes.
    
    * Made ast_include_rename() create a replacement ast_variable list node if
    the new filename is longer than the available space.  Fixes potential
    crash and memory leak.
    
    * Factored out ast_variable_move() from ast_variable_update() so
    ast_include_rename() can also use it when creating a replacement
    ast_variable list node.
    
    * Made the filename stuffed at the end of the struct a minimum allocated
    size in ast_variable_new() in case ast_include_rename() changes the stored
    filename.
    
    * Constify struct char pointers pointing to strings stuffed at the end of
    the struct for: ast_variable, cache_file_mtime, and ast_config_map.
    
    * Factored out cfmtime_new() to remove inlined code and allow some struct
    pointers to become const.
    
    * Removed the list lock from struct cache_file_mtime that was never used.
    
    * Added doxygen comments to several structure elements and better
    documented what strings are stuffed at the struct end char array.
    
    * Reworked ast_config_text_file_save() and set_fn() to handle allocation
    failure of the include file scratch pad object tracking blank lines.
    
    * Made ast_config_text_file_save() fn[] declared with PATH_MAX to ensure
    it is long enough for any filename with path.  Also reduced the number of
    container fileset buckets from a rediculus 180,000 to 1023.
