Merge migration capabilities and parameters in MigrationState and
deprecate migration capabilities QMP commands.

v2:

- TLS options:
  - Normalize to "abc"|"" during parameter handling.
  - Normalize to "abc"|NULL when exposing to rest of migration
    code.

- Reverted block_bitmap_mapping to truly optional in
  query-migrate-parameters. It's an API break to make it
  non-optional. Fortunately it doesn't get in the way of the rest of
  the series.

- Haven't made s->parameters a pointer. It breaks qdev properties,
  which need to use offsetof.
