The osp_sync_process_committed() cancels llog records one by one.
For each cancel it do open,transaction,mutex,write, etc. But most
of all cancels belongs to a single llog file. So they could
be combined.

The patch adds functions for cancelling array of indexes for a
llog file. And adds behavior and calls at
osp_sync_process_committed().
