[PATCH v3 00/14] simpletrace: refactor and general improvements

[Mads Ynddal]

From: Mads Ynddal <m.ynddal@samsung.com>

I wanted to use simpletrace.py for an internal project, so I tried to update
and polish the code. Some of the commits resolve specific issues, while some
are more subjective.

I've tried to divide it into commits so we can discuss the
individual changes, and I'm ready to pull things out, if it isn't needed.

v3:
 * Added __all__ with public interface
 * Added comment about magic numbers and structs from Stefan Hajnoczi
 * Reintroduced old interface for process, run and Analyzer
 * Added comment about Python 3.6 in ref. to getfullargspec
 * process now accepts events as file-like objects
 * Updated context-manager code for Analyzer
 * Moved logic of event processing to Analyzer class
 * Moved logic of process into _process function
 * Added new Analyzer2 class with kwarg event-processing
 * Reverted changes to process-call in scripts/analyse-locks-simpletrace.py
v2:
 * Added myself as maintainer of simpletrace.py
 * Improve docstring on `process`
 * Changed call to `process` in scripts/analyse-locks-simpletrace.py to reflect 
new argument types
 * Replaced `iteritems()` with `items()` in 
scripts/analyse-locks-simpletrace.py to support Python 3
