migration: export fewer options

A small number of migration options are accessed by migration clients,
but to see them clients must include all of options.h, which is mostly
for migration core code. migrate_mode() in particular will be needed by
multiple clients.

Refactor the option declarations so clients can see the necessary few via
misc.h, which already exports a portion of the client API.

migration: stop vm for cpr

When migration for cpr is initiated, stop the vm and set state
RUN_STATE_FINISH_MIGRATE before ram is saved. This eliminates the
possibility of ram and device state being out of sync, and guarantees
that a guest in the suspended state remains suspended, because qmp_cont
rejects a cont command in the RUN_STATE_FINISH_MIGRATE state.

delete, which simplifies the call sites. Shorten the function names
so the extra arg can be added more legibly. Hide the global notifier

migration/ram: Expose ramblock_is_ignored() as migrate_ram_is_ignored()

virtio-mem wants to know whether it should not mess with the RAMBlock
content (e.g., discard RAM, preallocate memory) on incoming migration.

So let's expose that function as migrate_ram_is_ignored() in
migration/misc.h

Migration Pull request

Everything that was reviewed since last PULL request:
- fix to control flow (eric)
- rearrange of hmp commands (juan)
- Make capabilities more consistent and coherent (juan)
Not all of them reviewed yet, so only the ones reviewed.

Later, Juan.

PD. I am waiting to finish review of the compression fixes to send
them.

It is only used there, so we can make it static.
