There are several stages during loadvm/savevm process. In different stage,
migration incoming processes different types of sections.
We want to control these stages more accuracy, it will benefit COLO
performance, we don't have to save type of QEMU_VM_SECTION_START
sections everytime while do checkpoint, besides, we want to separate
the process of saving/loading memory and devices state.
So we add three new helper functions: qemu_loadvm_state_begin(),
qemu_load_device_state() and qemu_savevm_live_state() to achieve
different process during migration.

I don't think this one can go in without the patch that follows which
uses these functions; we don't normally add functions
without the patch that uses them.
Agreed. If you want to add functions, you need new code that use them,
or make old code use them. It is up to you.
Got it, thanks, I'll merge this series with the one where we use them.
Thanks, Juan.
