[Xen-devel] [PATCH 1/2] opw: libxl: add convenience macros to qmp_send() in libxl_qmp.c

[Kelley Nielsen <kelleynnn@xxxxxxxxx>]

Update qmp_send() in libxl_qmp.c to use the new convenience macros
declared in libxl_internal.h. Uses GC_INIT at the top of the function,
and GC_FREE at the exit. Since GC_INIT returns a libxl__gc by reference
and not by value, remove the address operator from the left of the
variable gc where it is passed as a parameter.
