[PATCH V3 0/3] Cleanup: flexarray taking gc.

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

This two patches do a bit of cleanup in the memomy managment in libxl,
regarding the use of flexarray.

The first one modify flexarray_make to take gc as argument and update every
user in libxl to pass gc and to not call flexarray_free anymore.

The second one does some cleanup only in libxl_json to make it use the gc.

Change since v2:
  - New patch to expose gc_is_real to libxl.

Change since v1:
  - Change order of the two patch to not end up with leaks.
  - Add a comment on the first patch to tell why it OK to store the gc in the
    flexarray struct.
  - Keep the _free functions (libxl__json_object_free and flexarray_free, as
    they can be used if gc in NOGC.


Anthony PERARD (3):
  libxl: Move gc_is_real to libxl_internal.h.
  libxl: Have flexarray using the GC
  libxl_json: Use libxl alloc function.
