[PATCH 00/13] Migration PULL request (20230508 edition)

[Juan Quintela]

Hi

This is just the compression bits of the Migration PULL request for
20230428.  Only change is that we don't run the compression tests by
default.

The problem already exist with compression code.  The test just show
that it don't work.

Please apply, Juan.
