- 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

This clarifies and provides consistent for the command line arguments
usage text.
This adds a set of examples for running the rocket-chip emulator.

This, with riscv-fesvr modifications, enables the rocket-chip emulator
to understand (and error out) if a command line argument that will
eventually be consumed by HTIF looks bad and can error out quickly.
This relies on modifications to risc-fesvr to support getopt and the
exposure of what HTIF arguments exist via the `htif.h` header.
This removes the necessary preprocessing of riscv-fesvr arguments to
avoid situations where riscv-fesvr thinks that an argument is the
binary. Support for this is rolled into riscv-fesvr.
This changes the emulator to conform to POSIX-style options (e.g.,
short/'-' and long/'--') while preserving legacy option parsing (i.e.,
'+'). Options are read from the user until the first
non-option (either POSIX or legacy) is encountered. This and
everything following is assumed to be the binary and any arguments the
user wants to run on the emulator. All non-options are passed directly
to the DTM. This allows for the same option to be passed, safely, to
both the emulator and the binary, e.g., "+verbose".
This introduces a dependency on <getopt.h>.
Closes#484.
Two quick fixes that enable fpga_mem_gen to work with either Python 2 or
Python 3:
* Change an `xrange` instance to `range`
* Wrap the arguments of a bare `print` in parentheses
