[RFC 00/15] block job API

Hi all! The series aims to reach feature parity between job-* and block-job-* APIs and finally deprecate block-job-* APIs. 01: new type-based unions for QAPI 02-07: rework block-job-change and add similar job-change command 08: support set-speed in new API (as an option to job-change) 09: support soft-cancelling ready mirror job in new API (as an option to job-complete) 10-14: prepare query-jobs to substitute query-block-jobs 15: finally, deprecate old APIs RFC: the series are untested. I plan to move tests to using new APIs instead of deprecated ones in v2.
