====================
tc-testing: implement command timeouts and better results tracking

Patch 1 adds a timeout feature for any command tdc launches in a subshell.
This prevents tdc from hanging indefinitely.

Patches 2-4 introduce a new method for tracking and generating test case
results, and implements it across the core script and all applicable
plugins.
