Subject: psql: Add variable SERVICEFILE

This new psql variable can be used to check which service file has been
used for a connection.  Like other variables, this can be set in a
PROMPT or reported by an \echo, like these commands:
\echo :SERVICEFILE
\set PROMPT1 '=(%:SERVICEFILE:)%# '

This relies on commits 092f3c63efc6 and fef6da9e9c87 to retrieve this
information from the connection's PQconninfoOption.
