[patches] LIBDFP branch: Support for BID format

[Pete Eberlein <eberlein@xxxxxxxxxxxxxxxxxx>]

I've checked in some changes to the LIBDFP branch to support the DFP BID
format and cleanly separate it from the DPD format files.  This required
prefixing the symbol names in the soft-dfp directory with either __bid_
or __dpd_ to match those found in GCC.  The configure fragment detects
which DFP format is supported by GCC and the makefile uses this to
select the proper dpd or bid decNumber include directory.  The Implies
chain must still point to a soft-dfp dpd or bid subdirectory supported
by that platform.
