* smt: include firrtl statement names in SMT and btor2 output
* smt: remove println
* smt: make tests run again and fix stale ones
Apparently `private` classes aren't found by th sbt test runner.

* smt: add tests for assert name clashes
* smt: ensure unique signal names with a namespace
this fixes issues #1934

If there is more than one clock, this will be detected and
the user will be promted to run the StutteringClock transform.

This adds an experimental new SMTLib and Btor2 emitter
that converts a firrtl module into a format
suitable for open source model checkers.
The format generally follows the behavior of yosys'
write_smt2 and write_btor commands.
To generate btor2 for the module in m.fir run
> ./utils/bin/firrtl -i m.fir -E experimental-btor2
for SMT:
> ./utils/bin/firrtl -i m.fir -E experimental-smt2
If you have a design with multiple clocks
or an asynchronous reset, try out the new StutteringClockTransform.
You can designate any input of type Clock to be your
global simulation clock using the new GlobalClockAnnotation.
If your toplevel module instantiates submodules,
you need to inline them if you want the submodule
logic to be included in the formal model.
