The help text for -d in 'config' was aged, and the option processing
in 'config.com' was just different.  This harmonizes 'config.com' with
the instructions in INSTALL and both current reality.

Depending on user preferences, Configure might get something like
--PREFIX=blah just as well as --prefix=blah, or "SHARED" just as well
as "shared".  On VMS, let's therefore lowercase at least the portion
of the argument before a possible equal sign.

For good measure, we lowercase the arguments to be checked in
config.com as well.  The original argument is sent on to Configure,
however.

As part of this, change util/mkdef.pl to stop adding libraries to
depend on in its output.  mkdef.pl should ONLY output a symbol
vector.

Because symbol names can't be longer than 31 characters, we use the
compiler to shorten those that are longer down to 23 characters plus
an 8 character CRC.  To make sure users of our header files will pick
up on that automatically, add the DEC C supported extra headers files
__decc_include_prologue.h and __decc_include_epilogue.h.

Furthermore, we add a config.com, so VMS people can configure just as
comfortably as any Unix folks, thusly:
