steve b1fd927acb Named events really should be expressed with PEIdent
objects in the pform,

 Handle named events within the mix of net events
 and edges. As a unified lot they get caught together.
 wait statements are broken into more complex statements
 that include a conditional.

 Do not generate NetPEvent or NetNEvent objects in
 elaboration. NetEvent, NetEvWait and NetEvProbe
 take over those functions in the netlist.

steve e7efc2709a Redesign the implementation of scopes and parameters.
I now generate the scopes and notice the parameters
 in a separate pass over the pform. Once the scopes
 are generated, I can process overrides and evalutate
 paremeters before elaboration begins.

steve cb5fc54b5e Patch to synthesize unary ~ and the ternary operator.
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
 generator in t-xnf.cc to use XNF EQU devices to
 put muxs into function units.

 Rewrite elaborate_net for the PETernary class to
 also use the LPM_MUX device.
