[PATCH v3 0/6] migration removals & deprecations

since v2: - removed some more stuff which I missed: blk/inc options from hmp-commands.hx the entire ram-compress.h unused declarations from options.h unused compression functions from qemu-file.c - removed must_remove_block_options earlier in the 'blk' patch - added a deprecation warning to outgoing/incoming fd CI run: https://gitlab.com/farosas/qemu/-/pipelines/1272385260 v2: https://lore.kernel.org/r/20240426131408.25410-1-farosas@suse.de v1: https://lore.kernel.org/r/20240425150939.19268-1-farosas@suse.de 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.
