Revision 7e79421 (issue #484) makes emulator.cc rejecting any unrecognized
+arg "legacy" arguments, however, this breaks riscv-torture emulator tests
as it needs to pass +signature to the DTM.
I think it is actually impossible to check for unknown argument here
unless we hardcode a list of all arguments recognized by fesrv. Fix this
issue by passing all arguments starting with the first unknown argument
to DTM.
Updates #484.

* Configs: use a uniform syntax without Match exceptions
The old style of specifying Configs used total functions. The only way to
indicate that a key was not matched was to throw an exception. Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup. The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.
PLRU wasn't implemented correctly for the BTB, since it wasn't
increasing the priority on replacement, only on usage. Regardless,
this should be a second-order effect, so using FIFO always is fine.
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.
