[PATCH 0/5] qemu-img: convert to rST

[Peter Maydell]

This patchset converts the qemu-img documentation to rST format.
It includes a new Sphinx extension which handles parsing the .hx
files which provide documentation fragments for this manual.

The general approach follows the outline in the email I
sent the other day:
https://lists.gnu.org/archive/html/qemu-devel/2020-01/msg03786.html

The new Sphinx extension implements the hxtool-doc::
directive, which indicates where the assembled rST
document fragments should be inserted into the manual.
qemu-img-cmds.hx doesn't use the DEFHEADING or ARCHHEADING
directives, but the extension implements them (tested
with some local modifications to the .hx file to check
that they do the right thing).

As noted in the commit message for the qemu-img.texi conversion,
I have not attempted to tackle any of the muddle in the
current documentation structure or the repetition between
the manual document, the fragments in the .hx file and
the C code; this is a "simplest thing that works"
like-for-like conversion.

Another deliberate omission is that I have not attempted
to get links between our various Sphinx manuals (system,
interop, etc) working yet, as this is not totally trivial
and the odd minor missed hyperlink doesn't seem to me
to be a deal-breaker.

Sorry about the size of the main 'convert qemu-img'
patch, but it's unavoidable when converting a big
document between formats.

thanks

the makefile machinery)
