libxl: Deprecate libxl__domain_{unpause,resume}
These two functions are used from many places in libxl and need to
change to be able to accomodate libxl__ev_qmp calls and thus needs to
be asynchronous.
(There is also libxl__domain_resume_device_model in the mix.)
A later patch will introduce a new libxl__domain_resume and
libxl__domain_unpause which will make use of libxl__ev_qmp.
