[Qemu-devel] [PATCH 0/4 RFC] Introduce console for ringbuf backend

[Lei Li <lilei@linux.vnet.ibm.com>]

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:

Suggestions and comments are very welcome!

  monitor: introduce monitor_read_console

  qemu-char: export ringbuf_count
  hmp: add console support for ringbuf backend
