This v3 looks pretty decent, although I noted one significant error
and a few minor issues:

* in initStringInfoFromString, str->maxlen must be set to len+1 not len

* comment in exec_bind_message doesn't look like pgindent will like it

* same in record_recv, plus it has a misspelling "Initalize"

* in stringinfo.c, inclusion of pg_bitutils.h seems no longer needed

I guess the next question is whether we want to stop here or
try to relax the requirement about NUL-termination.  I'd be inclined
to call that a separate issue deserving a separate commit, so maybe
we should go ahead and commit this much anyway.
