Remove postmaster.c's reset_shared() wrapper function.
reset_shared just invokes CreateSharedMemoryAndSemaphores, so let's get rid of it and invoke that directly. This removes a confusing seeming-inconsistency between the postmaster's startup sequence and the startup sequence used in standalone mode.
