rvinterf: begin change to backslash escape output format
Right now throughout the rvinterf suite, any time we emit output that
is expected to be ASCII, but may contain non-printable garbage, we use
'cat -v' form of garbage character representation. Unfortunately, this
transformation is lossy (can't be reversed 100% reliably in the user's
wetware), hence we would like to migrate to C-style backslash escapes,
including doubling of any already-present backslashes - this escape
mechanism is lossless. Begin this change by converting the output
of RV and L1 traces in rvinterf and rvtdump.
