[PATCH v4 --for 4.6 COLOPre 03/25] tools/libxl: move domain resume code into libxl_dom_suspend.c

[Yang Hongyang <yanghy@cn.fujitsu.com>]

move domain resume code into libxl_dom_suspend.c.
pure code move.

libxl__domain_resume_device_model() will be used later by COLO,
so we are not making this func static.
