[PATCH 5/5] doc: Split buffer.rst out of api-summary.rst

[Matthew Wilcox (Oracle)]

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.
