tools/xenstore: introduce live update status block
Live update of Xenstore is done in multiple steps. It needs a status
block holding the current state of live update and related data. It
is allocated as child of the connection live update was started over
in order to abort live update in case the connection is closed.
Allocation of the block is done in lu_binary[_alloc](), freeing in
lu_abort() (and for now in lu_start() as long as no real live-update
is happening).
Add tests in all live-update command handlers other than lu_abort()
and lu_binary[_alloc]() for being started via the same connection
as the begin of live-update.
