Modified files:
    src/backend/bootstrap: bootstrap.c
    src/backend/postmaster: pgstat.c
    src/backend/storage/buffer: buf_init.c
    src/backend/storage/lmgr: lwlock.c proc.c
    src/backend/tcop: postgres.c

Log message:
    Remove ShutdownBufferPoolAccess exit callback, and do the work in
    ProcKill instead, where we still have a PGPROC with which to wait on
    LWLocks.  This fixes 'can't wait without a PROC structure' failures
    occasionally seen during backend shutdown (I'm surprised they weren't
    more frequent, actually).  Add an Assert() to LWLockAcquire to help
    catch any similar mistakes in future.  Fix failure to update MyProcPid
    for standalone backends and pgstat processes.
