 - Changes prompted by bug report that "Wed Aug 9 11:36:06 2000" could
   not be parsed.  The parse_rfc1123() code assumed there was an extra
   space after Aug and before "9".

   This change breaks the parsing into smaller functions to make the
   code easier to read and understand.

   I changed parsing of the "third" date format (asctime()) to use
   a buffer copy and strtok.  This makes it more flexible.  For example,
   we don't have to require strlen(s) < 24.
