This patch series aims at adding HMP console feature for ringbuf backend. It behaves like a serial console, which drops user into an interactive mode with ringbuf backend and takes user back to the monitor by the 'ctrl-]' escape sequence.
It would suspend the monitor, output the data that backed in the ringbuf backend to console first, and install a new readline handler to get input from console back into the ringbuf backend. Once escape sequence is detected, it will resume the monitor. This implementation is reworked based on Anthony's suggestions on the previous version: http://lists.gnu.org/archive/html/qemu-devel/2013-01/msg03888.html Suggestions and comments are very welcome!
