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.
