[libvirt] [PATCH] virsh: Use option alias for outmoded "--persistent"

Wed Mar 7 10:17:43 UTC 2012
Since VIR_DOMAIN_AFFECT_{LIVE,CONFIG,CURRENT} was created,
all new virsh commands use "--config" to represents the
persistent changing. This patch add "--config" option
for the old commands which still use "--persistent",
and "--persistent" is now alias of "--config".
tools/virsh.c: (use "--config", and "--persistent" is
alias of "--config" now).
cmdDomIfSetLink, cmdDomIfGetLink, cmdAttachDevice,
cmdDetachDevice, cmdUpdateDevice, cmdAttachInterface,
cmdDetachInterface, cmdAttachDisk, cmdDetachDisk
toos/virsh.pod: Update docs of the changed commands, and
add some missed docs for "--config" (detach-interface,
detach-disk, and detach-device).
