[PATCH v2 0/2] Increase amount of data for monitor to read

[Andrey Shinkevich via <qemu-devel@nongnu.org>]

The subject was discussed here:
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg00206.html

This series is a solution for the issue with QMP monitor buffered input.
A JSON little parser is introduced to separate QMP commands read from the
input buffer so that incoming requests do not overwhelm the monitor queue.
A side effect raised in the test #247 was managed in the first patch.
It may be considered as a workaround. Any sane fix suggested will be
appreciated.

Note:
This series goes after the Vladimir's one:
'[PATCH v3 00/25] backup performance: block_status + async"'
To make the test #129 passed, the following patch should be applied first:
'[PATCH v3 01/25] iotests: 129 don't check backup "busy"'.

v2:
  02: The static JSONthrottle object was made a member of the Chardev structure.
      The fd_chr_read functions were merged.
      The monitor thread synchronization was added to protect the input queue
      from overflow.
