These set of patches add few improvements to iotrace.
* Region limiting - allows setting an address and size where only
io operations that falls into that address are
logged.
* Timestamping - Timestamp every iotrace record with current timestamp
* dumping - iotrace dump command for dumping all records from buffer
in a readable fashion.
In terms of backwards compatibility, the timestamp is not backward
compatible as it changes the iotrace record. so if one developed an
offline parsing tool it will be broken.
I though of adding #ifdef specific for that, but eventually I didn't.
v2:
* fixed printf format
* added a fix when the buffer is full
