This commit introduces new internal bufmgr routines for marking shared buffers as dirty: * MarkDirtyUnpinnedBuffer() * MarkDirtyRelUnpinnedBuffers() * MarkDirtyAllUnpinnedBuffers() These functions provide an efficient mechanism to respectively mark one buffer, all the buffers of a relation, or the entire shared buffer pool as dirty, something that can be useful to force patterns for the checkpointer. MarkDirtyUnpinnedBufferInternal(), an extra routine, is used by these three, to mark as dirty an unpinned buffer. They are intended as developer tools to manipulate buffer dirtiness in bulk, and will be used in a follow-up commit.
