[PATCH RESEND 0/2] memory: Add tracepoints for log_sync

[Peter Xu <peterx@redhat.com>]

[this is a resend to hopefully drop '\r' in cover letter caused by git-publish
 that I should have just fixed; nothing changed inside]

It can help to identify which step is slow for migration dirty sync process.
We have migration_bitmap_sync_* trace events but it's still a bit coarse.

This should help us to cut migration_bitmap_sync() into finer grained small
steps when measurement is needed.

Please review, thanks.
