hypervisor: Implement start/stop_dirty_log for MSHV
This patch modify the existing live migration code
to support MSHV. Adds couple of new functions to enable
and disable dirty page tracking. Add missing IOCTL
to the seccomp rules for live migration.
Adds necessary flags for MSHV.
This changes don't affect KVM functionality at all.
In order to get better performance it is good to
enable dirty page tracking when we start live migration
and disable it when the migration is done.

hypervisor, vmm: Abstract the interfaces to start/stop dirty log
Following KVM interfaces, the `hypervisor` crate now provides interfaces
to start/stop the dirty pages logging on a per region basis, and asks
its users (e.g. the `vmm` crate) to iterate over the regions that needs
dirty pages log. MSHV only has a global control to start/stop dirty
pages log on all regions at once.
This patch refactors related APIs from the `hypervisor` crate to provide
a global control to start/stop dirty pages log (following MSHV's
behaviors), and keeps tracking the regions need dirty pages log for
KVM. It avoids leaking hypervisor-specific behaviors out of the
`hypervisor` crate.

This patch extends slightly the current live-migration code path with
the ability to dynamically start and stop logging dirty-pages, which

patch also contains a complete implementation of the two new methods
based on `kvm` and placeholders for `mshv` in the `hypervisor` crate.

Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.
vmm: hypervisor: split set_user_memory_region to two functions
Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.
MSHV has two calls -- one for creation and one for removal. It also
requires having the size field available because it is not slot based.
Split set_user_memory_region to {create/remove}_user_memory_region. For
KVM they still use set_user_memory_region underneath, but for MSHV they
map to different functions.
This fixes user memory region removal on MSHV.
