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.

Thanks to Larry Doolittle <LRDoolittle@lbl.gov>.
Add the LPM_MUX device, and integrate it with the
ternary synthesis from Larry. Replace the lpm_mux

attributes.
