Commit abb0b4fc03 moved the shared state for autoprewarm to a dynamic shared memory (DSM) segment, but it left apw_detach_shmem() in the on_shmem_exit callback list for the autoprewarm leader process. This is a problem because shmem_exit() detaches all the DSM segments prior to calling the on_shmem_exit callbacks, thus producing segfaults in the exit path for the autoprewarm leader process. To fix, move apw_detach_shmem() to the before_shmem_exit callback list. This commit also adds a check to pg_prewarm's test that the server shut down normally. It might be worth making this a common check for all shutdowns in TAP tests, but that is left as a future exercise.
