[PATCH 0/3] convert qemu-nbd, qemu-block-drivers to rST

[Peter Maydell]

This patchset converts the qemu-nbd and qemu-block-drivers
documentation from texinfo to rST. For both of these,
currently the documentation is in texinfo, which we present
to the user as:
 * a manpage
 * a section of the qemu-doc HTML documentation

The conversion results in the docs being in rST format,
presented to the user as:
 * a manpage
 * a section of one of the Sphinx manuals (interop/
   for qemu-nbd, and system/ for qemu-block-drivers)

The first patch is the same as the "qemu-nbd: Convert invocation
documentation to rST" patch I sent a couple of days ago, except that
I have folded some of the long Makefile lines as Eric suggested.

Patch 2 creates the new 'system' manual; this has always
been in our plan for the docs as described in
https://wiki.qemu.org/Features/Documentation
but this is the first point where we have some actual
content for it.

Patch 3 converts the qemu-block-drivers docs/manpage.  As noted in
the commit message for that patch, this requires dropping a minor
cross-reference from the '-cdrom' option documentation to this
(because they're no longer in the same big texinfo document).  There
is also a slightly ugly compromise in the manpage output in order to
provide better HTML output, which is forced on us by limitations in
Sphinx.

Apologies for the size of patch 3, but a single big-bang conversion
of this 1000 page document seemed better than artificially trying to
split it somehow, since only one of the two formats can actually
produce the manpage at once.

PS: the old docs/qemu-block-drivers.texi is not covered by
any MAINTAINERS section, so I haven't added the new
docs/system/qemu-block-drivers.rst anywhere either.
Perhaps it should go in the "Block layer core" section?

thanks
