Tracker: style fixes to PoseList class

Add virtual directory feature to Tracker

Similar to stored queries, files of the virtual directory type behave
like directories -- i.e. they open in a list-mode Tracker window and
show up as an item with submenu in navigation menus. The file itself is
a plain text file in driver settings format. It can have an arbitrary
number of "directory" entries, which specify the paths of (actual)
directories for which the virtual directory provides a merged view. The
view will not show duplicate entries. For non-directory entries the
first one encountered (according to the order the directory paths are
specified in the file) will be shown. A subdirectory entry will again
behave like a virtual directory.

The support in Tracker isn't perfect yet. I'm afraid major refactoring
would be necessary to get it there.

The virtual directory file type uses a differently colored version of
the folder icon. Alternatives welcome.

Tracker: Style fixes, should have no functional change

Tracker: various issues regarding filtering

1. A BRefFilter-ed PoseView wouldn't keep monitoring files after its opening
thus not picking up files that happen to fit the filter thereafter (mime attr
updated, etc..)
2. A filtered PoseView wouldn't get updated when:
a) a column was added or removed
b) a file was renamed
c) a file was moved
3. Harmonize the way BRefFiltering and Type-ahead filtering are working. Both
can be used together.
4. The handler for AttributeChanged() wasn't working properly if link(s) of a
changed model was/were its siblings.
5. Broken links weren't detected/updated (it nows monitor the lost target
parent directory, and wait for the target creation to show the link fixed)

This is a big change (even more considering the 'critical-ness' of the component)
Testing is MUCH welcome!

Should fix #4254, #5381, #1717 (and maybe others)

WIP: Yet more style fixes, mostly 80 char violations.

Style changes in Tracker, no functional change.

Manual whitespace cleanup
Change instances of const char * to const char*
Convert /* */ C style comments to // C++ style comments

Reworked the handling of periodically updated poses (currently only ones with a volume space bar):

* Addad global list where poses that need periodic updates can be registered with a callback
* Use this mechanism for poses with a volume space bar
* Create only one BVolume when the BPose is created for a volume, instead of every time the free space is calculated
* On Pulse() the global list is used to update all of the registered periodic update poses
* As the poses know their volume, it is no longer necessary to use a BVolumeRoster to loop through each volume on each Pulse()
* Removed the now superfluous SendNotices() mechanism
* Removed corresponding watching / handling of these notices in BPoseView

The BPoseView did a linear search for each volume pose on each Pulse() before. What's more it did this once for each mounted volume as it did get one individual notice for each of them. To get these volumes a BVolumeRoster was used to loop through the volumes, but then the BPose did still create a new BVolume to actually calculate the free space! I'm surprised that it did not suck away more performance with this method...

Anyway, this should bring down BVolume construction and update overhead down to a minimum and hopefully fix ticket #1247.
