[00/12] migration: Yet another round of atomic counters

Message

Hi

Goal of the whole series was to be able to move rate_limit logic to
not use qemu_file.  Goal achieved.

Removal of trasnferred atomic counter.

After this series, we have three atomic counters:
- multifd_bytes
- rdma_bytes
- qemu_file_trasferred

And we only need to setup one (and only one) of these each time that
we sent anything.

Please review.

Later, Juan.

Juan Quintela (12):
  qemu-file: We only call qemu_file_transferred_* on the sending side
  qemu_file: Use a stat64 for qemu_file_transferred
  qemu_file: total_transferred is not used anymore
  migration: Use the number of transferred bytes directly
  qemu_file: Remove unused qemu_file_transferred()
  qemu-file: Remove _noflush from qemu_file_transferred_noflush()
  migration: migration_transferred_bytes() don't need the QEMUFile
  migration: migration_rate_limit_reset() don't need the QEMUFile
  qemu-file: Simplify qemu_file_get_error()
  migration: Use migration_transferred_bytes()
  migration: Remove transferred atomic counter
  qemu-file: Make qemu_fflush() return errors
