injection_points: Introduce runtime conditions This adds a new SQL function injection_points_set_local() that can be used to force injection points to be run only in the process where they are attached. This is handy for SQL tests to: - Detach automatically injection points when the process exits. - Allow tests with injection points to run concurrently with other test suites, so as such modules do not have to be marked with NO_INSTALLCHECK.
Currently, the only condition that can be registered is for a PID. This could be extended to more kinds later, if required, like database names/OIDs, roles, or more concepts I did not consider. Using a single function for SQL scripts is an idea from Heikki Linnakangas.
