Bug fixing, features for powerdebug

source code: http://git.linaro.org/gitweb?p=tools/powerdebug.git;a=summary
git tree: git://git.linaro.org/tools/powerdebug.git

Status:
In progress

[work item: Generic tree engine]
Adding this will have several benefits for the powerdebug code:
  * factor out the code between the different components
  * make the code more maintainable
  * will allow to add the next features more quickly

The following Work items were moved to https://blueprints.launchpad.net/linaro-powerdebug/+spec/powerdebug-new-features
[daniel-lezcano] Clock: Refresh on inotify events: TODO

Clock: Refresh on inotify events, This workitem is not implementable as specified. The inotify is *not* recursive so we need to add a inotify watch per relevant directory or file which can be very expansive in terms of resources. I propose to change this approach and add a "watchpoint" when selecting a specific item (eg. a clock). This watchpoing will display or log the changes on the watchpoint. This approach is similar to gdb and in my opinion more adequate for a debugging tool.
