Richard Levitte e84193e43d unified build scheme: add a "unified" template for VMS descrip.mms
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:

    @config

# This script will translate any SYMBOL_VECTOR item that has a translation
# in CXX$DEMANGLER_DB. The latter is generated by and CC/DECC command that
# uses the qualifier /REPOSITORY with the build directory as value. When
# /NAMES=SHORTENED has been used, this file will hold the translations from
# the original symbols to the shortened variants.
#
# CXX$DEMAGLER_DB. is an ISAM file, but with the magic of RMS, it can be
# read as a text file, with each record as one line.
#
# The lines will have the following syntax for any symbol found that's longer
# than 31 characters:
#
# LONG_symbol_34567890123{cksum}$LONG_symbol_34567890123_more_than_31_chars
#
# $ is present at the end of the shortened symbol name, and is preceded by a
# 7 character checksum. The $ makes it easy to separate the shortened name
# from the original one.
