Here's a first attempt at a new documentation chapter. This goes in
part "Server Programming", just after the SPI chapter.
I just noticed that worker_spi could use some more sample code, for
example auth_counter was getting its own LWLock and also its own shmem
area, which would be helpful to demonstrate I think.
