[PATCH 0/6] migration removals & deprecations

Hi everyone, Here's some cleaning up of deprecated code. It removes the old block migration and compression code. Both have suitable replacements in the form of the blockdev-mirror driver and multifd compression, respectively. There's also a deprecation for fd: + file to cope with the fact that the new MigrationAddress API defines transports instead of protocols (loose terms) like the old string API did. So we cannot map 1:1 from fd: to any transport because fd: allows *both* file migration and socket migration.
