[Qemu-devel] [PATCH V6 11/13] monitor: support sub command in auto completion

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

This patch allow auto completion work normal for sub command case,
"info block [DEVICE]" can auto complete now, by re-enter the completion
function. In original code "info" is treated as a special case, now it
is treated as a sub command group, global variable info_cmds is not used
any more.

"help" command is still treated as a special case, since it is not a sub
command group but want to auto complete command in root command table.
