Subject: doc: split buffer.rst out of api-summary.rst

Buffer heads are no longer a generic filesystem API but an optional
filesystem support library. Make the documentation structure reflect
that, and include the fine documentation kept in buffer_head.h. We could
give a better overview of what buffer heads are all about, but my
enthusiasm for documenting it is limited.

+Buffer Heads
+============
+
+Linux uses buffer heads to maintain state about individual filesystem blocks.
+Buffer heads are deprecated and new filesystems should use iomap instead.
