[PATCH V3 00/10] Set dirty log on qemu-xen.

[Anthony PERARD <anthony.perard@citrix.com>]

Note: Now depend on "Cleanup: flexarray taking gc" sent earlier.


This patch series enables libxl to set dirty log on QEMU upstream during
migration through a new QMP command.

The success of the call depends on the presence of the specific QMP command
xen-set-global-dirty-log in QEMU. Patches for this command have been sent.

There is several patches that cleanup a bit the libxl_json/qmp codes.

Change since v2:
  - New patch to remove the unused JSON_ERROR enum value.
  - New patch to replace JSON_TRUE/FALSE by JSON_BOOL.
  - libxl__json_object_to_yajl_gen will now abort() if there is a wrong type
    for a node.
  - The macro QMP_PARAMETERS_SPRINTF now expect the var gc to be present in the
    environment of the caller.
  - The last patch remove the all check instead of just the return error for
    qemu-xen.

Changes since v1:
  - Use libxl allocation function with NOGC when requiered.
  - No more check of failed allocation.
  - New qmp_run_command function, to factorize the libxl_qmp code.
  - cleanup ...
