I added the source-able piece of shell snippet from the "shellenv"
branch to rumprun. Sourcing it sets the env for rumpremote. It also
adds a "listcmds" command for, you guessed it, listing the available
rumpremote commands. See usage example at the end of this mail.
The only potential usage issue I see is that if an expected rumpremote
command is missing, a host command will be run instead. I considered
overriding the existing $PATH completely when rumpremote.sh is sourced,
but that would also take away things like piping command output to grep,
less, etc. That said, I'm not sure it's anything to greatly worry about.
I think the "shellenv" can be considered dead now.
