VMS: move copy_argc to its own module and make it an aux source

copy_argv was never initialization code.

Make it self-cleaning too.

-     * 2011-03-22 SMS.
-     * If we have 32-bit pointers everywhere, then we're safe, and
-     * we bypass this mess, as on non-VMS systems.
-     * Problem 1: Compaq/HP C before V7.3 always used 32-bit
-     * pointers for argv[].
-     * Fix 1: For a 32-bit argv[], when we're using 64-bit pointers
-     * everywhere else, we always allocate and use a 64-bit
-     * duplicate of argv[].
-     * Problem 2: Compaq/HP C V7.3 (Alpha, IA64) before ECO1 failed
-     * to NULL-terminate a 64-bit argv[].  (As this was written, the
-     * compiler ECO was available only on IA64.)
-     * Fix 2: Unless advised not to (VMS_TRUST_ARGV), we test a
-     * 64-bit argv[argc] for NULL, and, if necessary, use a
-     * (properly) NULL-terminated (64-bit) duplicate of argv[].
-     * The same code is used in either case to duplicate argv[].
-     * Some of these decisions could be handled in preprocessing,
-     * but the code tends to get even uglier, and the penalty for
-     * deciding at compile- or run-time is tiny.
