   This is a little tricky since it should be portable.

   The openVMS object file has 'variable length' which means that
   read() returns data in chunks of (hopefully) correct and expected
   size.  The linker (and other tools on VMS) depend on that. Unix
   doesn't know about 'formatted' files, so reading and writing such
   an object file in a Unix environment is not trivial.

   With the tool 'file' (available on all VMS FTP sites), one
   can view and change the attributes of a file.  Changing from
   'variable length' to 'fixed length, 512 bytes' reveals the
   record size at the first 2 bytes of every record.  The same
   may happen during the transfer of object files from VMS to Unix,
   at least with UCX, the DEC implementation of TCP/IP.

   The VMS format repeats the size at bytes 2 & 3 of every record.

   On the first call (file_format == FF_UNKNOWN) we check if
   the first and the third byte pair (!) of the record match.
   If they do it's an object file in an Unix environment or with
   wrong attributes (FF_FOREIGN), else we should be in a VMS
   environment where read() returns the record size (FF_NATIVE).

   Reading is always done in 2 steps:
    1. first just the record header is read and the size extracted,
    2. then the read buffer is adjusted and the remaining bytes are
       read in.

   All file I/O is done on even file positions.  */
