V0.8: Rework the NetLatch and back end code.
...
This patch reworks the NetLatch class to better match the NetFF class
(e.g. it adds a place for the async controls and value, adds a dump
routine, etc.) and moves it into the normal netlist.{h,cc} files. It
removes the unused Aload and Sload routines, etc. from the NetFF class.
It switches the latch to use the existing ff object to pass information
to the target and uses the existing FF routines as applicable.
ivl_lpm_async_clr()
ivl_lpm_async_set()
ivl_lpm_aset_value()
ivl_lpm_clk() for the gate
ivl_lpm_data()
ivl_lpm_q()
It adds support for generating a latch UDP just like is done for the
D flip-flop in the tgt-vvp code generator and fixes a bug in the
generation of the clear signal when both the Aclr and Aset signals
clear the register.

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.
