The type for the copy-before-write timeout in nanoseconds was wrong.
By being just uint32_t, a maximum of slightly over 4 seconds was
possible. Larger values would overflow and thus the 45 seconds set by
Proxmox's backup with fleecing, resulted in effectively 2 seconds
timeout for copy-before-write operations.

Biggest change is that AioContext locking got removed, but no changes
required other than dropping the calls to acquire and release it. As a
consequence, the single parameter for the bdrv_graph_wrlock() call got
removed which also required adaptation.
QAPI docs became stricter requiring to document all members.
Other minor changes:
- Single parameter from migration_is_running() was dropped.
- qemu_mutex_(un)lock_iothread() got renamed to bql_(un)lock().
