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.

76c5fd0c0c travis: Use newer infrastructure, but require sudo for additional disk space. 
This is because as of Dec 12, 2017, Travis changed their container images and seem
to give slightly less disk space. Using a sudo image gives more disk space.

7ae6bf7611 Arguments clarification, add examples 
This clarifies and provides consistent for the command line arguments
usage text.

This adds a set of examples for running the rocket-chip emulator.

1aa87f6578 Make emulator.cc understand HTIF arguments 
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.

3ead9a5d2d Move check on VCS inside riscv-fesvr 
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.

1d3fa07c44 debug: print failures when debug tests fail, so we can see why it is failing on Travis 
Cleanups, and print out log names ASAP.

Factor out gdbserver common invocation into GDBSERVER (fixing
--print-failtures).
Add --print-log-names to that command so the logfiles can be inspected
while the simulation is still running.
`RISCV=... cmd` is more idiomatic than `export RISCV=... && cmd`

e82328336e Add in a SimJTAG to connect to OpenOCD's remote-bitbang interface. 
This is simpler than JTAGVPI and is supported better by Verilor.
It is also the same thing Spike uses.

Memory regions that are uncacheable or have get/put effects should not
reside in the D$, so there is no need to flush them.

ee1a9485df Enforce physical-address canonicalization 
When xLen > paddrBits, enforce that physical addresses are zero-extended.
This works by checking that the _virtual_ address is _sign_-extended, then
checking that its sign is positive.
