chomp PQerrorMessage() in backend uses

Browse Source 
PQerrorMessage() returns an error message with a trailing newline, but
in backend use (dblink, postgres_fdw, libpqwalreceiver), we want to have
the error message without that for emitting via ereport().  To simplify
that, add a function pchomp() that returns a pstrdup'ed string with the
trailing newline characters removed.
