sphinx: adopt kernel readthedoc theme
The default "alabaster" sphinx theme has a couple shortcomings: - the navbar moves along the page - the search bar is not always at the same place - it lacks some contrast and colours The "rtd" theme from readthedocs.org is a popular third party theme used notably by the kernel, with a custom style sheet. I like it better, perhaps others do too. It also simplifies the "Edit on Gitlab" links. Tweak a bit the custom theme to match qemu.org style, use the QEMU logo, and favicon etc. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Bin Meng <bmeng.cn@gmail.com> Message-Id: <20210323115328.4146052-1-marcandre.lureau@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com>
