  1. Add InjectionPointList() to retrieve list of injection points 

    This hides the internals of the shmem array lookup, allocating the
result in a palloc'd array usable by the caller.

  2. injection_points: Add function to flush injection point data to disk 

    The function injection_points_flush() can be called in a session to
persist to disk all the injection points currently attached to the
cluster.  These are saved in file called injection_points.data at the
root of PGDATA, and loaded by the cluster at startup with all the points
registered automatically attached.

This will be useful to test scenarios where injection points need to be
for example attached at very early stages of startup, before it is
possible to attach anything via SQL.

  3. Add regression test for 2PC visibility check on standby 

    This adds some test coverage for a defect fixed in 2e57790, where
the only reliable test back then was to use a hardcoded sleep().

This test relies on an injection point that is persisted across a node
restart, so as it is possible to cause the checkpointer to wait when
configuring the shared memory state of shared_preload_libraries at a
very early startup stage.

Reverting 2e57790 causes the test to fail, and it passes on HEAD.
