[PULL 29/33] docs: Generate qemu.1 manpage with Sphinx

[Peter Maydell <peter.maydell@linaro.org>]

Generate the qemu.1 manpage using Sphinx; we do this with a new
top-level rst source file which is just the skeleton of the manpage
and which includes .rst.inc fragments where it needs to incorporate
sections from the larger HTML manuals.
