Fix tracecontext seek backward underflow
Fix a problem with the detailed event list "seek backward". In the following
condition:
- Long interval between events (e.g. generated with power management suspend).
- Happening close to trace start.
- Trace start near 0s 0ns.
The substraction could underflow. Fix this by comparing the time to substract
and floor to trace start time if it would underflow.
The visible effect was that the detailed event list is seeked to the end of the
trace rather than the previous event when going "up" one event prior to the
suspend begin.

Make the synchronization module interfaces more generic
Instead of taking NetEvents and Packets, public interfaces take Events,
Messages and Exchanges. These are specialized into other structures for TCP.
This is to support the eventual integration of algorithms based on other event
types, like UDP.

Add a unittest program for clock synchronization modules
Allows to test matching and analysis modules with data read from text files.
Includes some sample data for simple good and bad (unsynchronizable) cases.

Add convex hull algorithm-based synchronization
This analysis module implements an algorithm that provides a garantee that the
synchronization will not result in inverted messages. It is now the default
algorithm, over linear regression.
