Promote pg_dumpall shell/connstr quoting functions to src/fe_utils.

Rename these newly-extern functions with terms more typical of their new
neighbors.  No functional changes; a subsequent commit will use them in
more places.  Back-patch to 9.1 (all supported versions).  Back branches
lack src/fe_utils, so instead rename the functions in place; the
subsequent commit will copy them into the other programs using them.

Security: CVE-2016-5424
