From: Steve Sistare <steven.sistare@oracle.com>

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.
