[Tracker] REVIEW: 'data-provider-monitor-interface' branch

[Martyn Russell <martyn lanedo com>]

Hi all,

I've recently completed a feature branch to allow 3rd party data 
provider implementations to notify when data has been updated. This 
mimics the existing TrackerMonitor API that already exists but 
incorporates it into the existing TrackerDataProvider interface.

The branch is available here:

https://git.gnome.org/browse/tracker/log/?h=data-provider-monitor-interface

Please review. I plan to do an unstable release with this soon.

The TrackerMonitor code is untouched and the TrackerFileDataProvider 
(which is the file system and default implementation for 
tracker-miner-fs) simply connects all signals up to this. I've done it 
this way to preserve history and code clarity in tracker-monitor.c and 
to keep things as simple as possible right now.

The interface specifically is defined here:
https://git.gnome.org/browse/tracker/tree/src/libtracker-miner/tracker-data-provider.h?h=data-provider-monitor-interface

Internally, we now have removed some of the places where a 
TrackerIndexingTree is required because a TrackerDataProvider already 
exists (in classes like TrackerFileNotifier, etc). This is because the 
Most classes in connection with the data provider need to know about the 
indexing tree.

Thanks,
