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.

/* * Limits on FFS filenames and pathnames * * The deepest pathname allowed is one of the form /1/2/3/4/5/6, where the * last component may be a file, a directory or a symlink; if this last * component is a directory, it has to be empty, because any child of * that directory would violate the depth limit. * * The proper FFS pathname form begins with a slash (all pathnames must * be absolute, no Unix processes in the fw means no current directories), * has exactly one slash in each separating place (no double slashes), * and no trailing slash except in the special case of the root directory, * whose full pathname is "/". * * Each component name is [1,20] characters long; combining this limit * with the maximum depth of 6 puts the maximum length of a properly-formed * full pathname at 126 characters. */ #define MAX_FN_COMPONENT 20 #define MAX_NAME_DEPTH 6 #define MAX_FULL_PATHNAME ((MAX_FN_COMPONENT+1) * MAX_NAME_DEPTH)
