Add an additional "caps" argument to the libxenmanage functions to

Update the xenstored callers at the same time.
Luckily the interface was only introduced in the current devel cycle,
so no need for playing "stable interface" games. :-)
Yes :)
Having said that, for compatibility, will we need some way to query Xen
for a mask of valid capability bits? That way a caller can
differentiate between "this domain doesn't have a capability" and "this
hypervisor doesn't support a capability."
