This patch updates the Documentation/filesystems/vfs.txt document.  I
rearranged and rewrote parts of the introduction chapter and added better
headings for each section.  I also added a description for the inode
rename() operation which was missing and added links to some useful
external VFS documentation.

Convert to proper kernel-doc format.

Some have extra blank lines (not allowed immed.  after the function name)
or need blank lines (after all parameters).  Function summary must be only
one line.

Colon (":") in a function description does weird things (causes kernel-doc
to think that it's a new section head sadly).
