[Qemu-devel] [RFC PATCH 37/56] blockjob: Make BlockJobInfo and event speed unsigned in QAPI/QMP

[Markus Armbruster]

Byte rates should use QAPI type 'size' (uint64_t).  BlockJobInfo
member @speed and parameter @speed of events BLOCK_JOB_COMPLETED,
BLOCK_JOB_CANCELLED, BLOCK_JOB_READY are 'int' (int64_t).

block_job_query(), block_job_event_completed(),
block_job_event_cancelled(), block_job_event_ready() all get it from
BlockJob member @speed, implicitly converting from uint64_t (since the
commit before previous).  The conversion is safe, because
block_job_set_speed() won't set speeds above INT_MAX.

Change the BlockJobInfo member and the event parameters to 'size', for
QAPI/QMP consistency.
