* src/libtracker-common/tracker-thumbnailer.h:
	* src/libtracker-common/tracker-albumart.h: Added preprocessor
	checks for __LIBTRACKER_COMMON_INSIDE__ which were missing.

	* src/libtracker-common/tracker-albumart.[ch]: 
	* src/tracker-extract/tracker-extract-mp3.c: Fixed coding style
	issues.

	* src/libtracker-common/tracker-albumart.[ch]: 
	* src/tracker-extract/tracker-extract-albumart.c:
	* src/tracker-extract/tracker-main.[ch]: Only create one
	TrackerHal object during the life time of tracker-extract instead
	of for EVERY file which has album art (which is quite a lot). This
	seems to be showing an increase of 2x the speed now for
	tracker-extract. 

	* src/tracker-indexer/tracker-main.c: (main): Added print
	statement like we have in the daemon so we know when the process
	is finished and returning to the cmd line.

	* tests/tracker-extract/tracker-extract-test-utils.c:
	(tracker_test_extract_file_access): Added tracker_main_get_hal()
	fixes to ensure the tests build.
