Cary R 678dd7bdaa V0.8: Add support for negedge FF and Aclr/Aset both clear. 
This patch fixes the bugs reported in pr1757438. These are fpga/edif
code generation bugs. For a DFF we need to add an inverter for a
negedge device and if both the Aclr and Aset signals clear the FF
we need to create the OR of these signals to drive the Aclr pin.

Cary R ae14a58bff V0.8: Remove deprecated #ident and fix some other compile warnings 
This patch removes #ident since it is deprecated in recent gcc
versions. It also removes all the CVS comments and fixes a few
other compilation warnings. There are still a few compilation
warnings, but this takes care of most of them. Fixing the rest
will require a bit more thought.
