Peter Krempa ecdd929761 qemu: capabilities: Add QEMU_CAPS_BLOCKDEV_REOPEN 
This capability will be asserted once qemu stabilizes 'blockdev-reopen'.
For now we just add the capability so that we can introduce some code
that will use the reopening call. This will show our willingness to
adopt use of reopen and help qemu developers stabilize it.

* Internal flags to keep track of qemu command line capabilities
*
* As a general rule these flags must not be deleted / renamed, as
* they are serialized in string format into the runtime XML file
* for guests, and new libvirt needs to cope with reading flags
* defined by old libvirt.
*
* The exception to this rule is when we drop support for running
* with older QEMU versions entirely. When a flag is no longer needed
* we temporarily give it an X_ prefix to indicate it should no
* longer be used in code. Periodically we can then purge all the
* X_ flags and re-group what's left.
