This costs us an extra getsockname(2) call per connection, so default
to off.

SHM clients can tell the state of this option by the number of fields
in SessionOpen: 3 (off) or 4 (on).

Make an executive decision, and change the regsub() replacement specifiers to
get something which is consistent and nontroubling for URL and query strings.

Since $ and & both are heavily used in query strings, we (DES & I)
have chosen to use \0 ... \9 for replacement indicators, with \0
being the "all matched text" replacement and \1...\9 replacing
with tne N'th paranthesized subexpressions.
