    libxl: create xenstore nodes for control/feature-XXX flags
    
    The xenstore-paths documentation specifies various control/feature-XXX
    flags to allow a guest to tell a toolstack about its abilities to
    respond to values written to control/shutdown. However, because the
    parent control xenstore key is created read-only to the guest, unless
    empty nodes for the feature flags are also created reat/write by the
    toolstack, the guest will not be able to set any flags.
    
    This patch adds code to create all specified feature flag nodes at
    domain creation time.
