This way we can read it from any thread.
I checked that it gives the same value as the current one. We never
use two qemu_files at the same time.

Just create a variable for it, the same way that multifd does. This
way it is safe to use for other thread, etc, etc.

Since previous commit, we calculate how much data we have send with
migration_transferred_bytes() so no need to maintain this counter and
remember to always update it.

Once there rename it to migration_transferred_bytes() and pass a
QEMUFile instead of a migration object.

These way we can make them atomic and use this functions from any
place. I also moved all functions that use rate_limit to
migration-stats.
Functions got renamed, they are not qemu_file anymore.
qemu_file_rate_limit -> migration_rate_exceeded
qemu_file_set_rate_limit -> migration_rate_set
qemu_file_get_rate_limit -> migration_rate_get
qemu_file_reset_rate_limit -> migration_rate_reset
qemu_file_acct_rate_limit -> migration_rate_account.

It is lousely based on MigrationStats, but that name is taken, so this
is the best one that I came with.

If you have any good suggestion for the name, I am all ears.
migration_stats is just too long, and it is going to have more than
ram counters in the near future.

There is already include/qemu/stats.h, so stats.h was a bad idea.
We want this file to not depend on anything else, we will move all the
migration counters/stats to this struct.
