Merge branch 'kerneldoc2' into docs-next

So once upon a time I set out to fix the problem reported by Tobin wherein
a literal block within a kerneldoc comment would be corrupted in
processing.  On the way, though, I got annoyed at the way I have to learn
how kernel-doc works from the beginning every time I tear into it.

As a result, seven of the following eight patches just get rid of some dead
code and reorganize the rest - mostly turning the 500-line process_file()
function into something a bit more rational.  Sphinx output is unchanged
after these are applied.  Then, at the end, there's a tweak to stop messing
with literal blocks.

If anybody was unaware that I've not done any serious Perl since the
1990's, they will certainly understand that fact now.

STATE_FIELD describes a parser state that can handle any part of a
kerneldoc comment body; rename it to STATE_BODY to reflect that.

The $in_purpose variable was a hidden substate of STATE_FIELD; get rid of
it and make a proper state (STATE_BODY_MAYBE) instead.  This will make the

 - Moved the 'Including kernel-doc comments' section to the end of

   how to integrate it.

   to know what to document before telling them how to do it.
 - Rewrite the 'Writing kernel-doc comments' section, integrating
   the 'Recommendations' subsection and a paragraph from 'How to format
   kernel-doc comments'.
 - Remove the paragraph about the kernel-doc script; we're supposed to
   be teaching people how to use punctuation to write pretty documentation,
   not documenting the build tooling.
 - Split the 'Parameters and member arguments' section into 'Function
   parameters' and 'Members'.  Structure members are not commonly
   referred to as arguments.
 - Integrate the 'private:' and 'public:' tag descriptions into the
   'Members' section.
 - Move the 'In-line member documentation comments' subsection up to be
   with the 'Members' section.
