JTAG: Use new withClock way of overriding clocks (#1072) 
* JTAG: Use new withClock way of overriding clocks

the override clock way is deprecated

* JTAG: use withClock instead of override clock

* JTAG:  extend Module for ClockedCounter

* JTAG: Don't use deprecated clock constructs

* JTAG: Remove another override_clock

* Rename "NegativeEdgeLatch"

because it's not a latch, it's just a register on the negative edge of the clock.

* Use the appropriately named NegEdgeReg

* JTAG: Rename another NegativeEdgeLatch

- adds a mutable singleton (PlusArgArtefacts) to store information
  about Rocket PlusArgs
- adds methods to PlusArgArtefacts to emit C snippets that are
  consumed by emulator.cc for correct argument parsing and help text
  generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
  ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs

enhance error message when debug enabled 
This commit enhances the error message when the user enables waveform dump at runtime but forgets to enable the compile time define.

remove string type ambiguity in header 
I ran into a compilation issue.

This link explains the problem well: https://stackoverflow.com/a/5499222/3736700

For example, in a header file, it is generally not considered a good idea to put the line using namespace std; (or to use any namespace, for that matter) because it can cause names in files that include that header to become ambiguous. In this setup, you would just #include <string> in the header, then use std::string to refer to the string type.

Update TestDriver module to support FSDB 
Add support for FSDB waveform dumping using existing API.  Feature is enabled using +define+FSDB.

Change has not been fully regressed (i.e., please don't pull blindly).  Impact on existing knobs is minimal, should not affect existing functionality.  Automated Travis builds should be sufficient to assess.

Alternatively could using +define+VCS.  Chose to introduce new define because multiple simulators support FSDB dumping.
