Someday, it would be really nice to expand
http://libvirt.org/hvsupport.html to say which flags are supported since
which version (that is, knowing that virDomainStartFlags() is available
is interesting, but it is even more interesting to know _which_ drivers
support which flags, and when support for those flags was added).

But if we ever do come up with a way to list per-flag support for APIs,
I think automating it to the hvsupport.html page is sufficient; we don't
also need to call it out in the libvirt.c documentation.  So I'm okay
with the complaint of not needing the 'since 1.0.1' here.
