[Qemu-devel] [PATCH V9 05/15] monitor: avoid use of global *cur_mon in readline_completion()

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

Now all completion functions do not use *cur_mon any more, instead
they use rs->mon. In short, structure ReadLineState decide where
the complete action would be taken now.

Tested with the case that qemu have two telnet monitors, auto
completion function works normal.
