Remove the CVS information in the documentation and the remaining tgt-* directories.
The last patch to add key charasters apparently wasn't enough for gperf 2.7.
When I added the SV/Verilog-AMS keywords I forgot to update the gperf keys in autoconf.sh. This patch makes them match the Makefile.
Collapse all the configure checks to a single configure script in the root of the source tree. This makes the configure process run a lot faster, expecially on Windows systems that are slower in general.
These files are (were) related to the old vvm backend that is no longer in use. Thus, these files are dead code.
gperf command line changed in Makefile.in as of commit cde87ed this patch propagates that change to autoconf.sh
