(I saw bug 195161, which is somehow related to this one - both require more sophisticated handling of file/directory paths.)

Currently it is possible to have multiple Amarok-on-Linux instances access the same collection database (which may be located on a home server, for example). For this to work, the music directory must be at the exact same location, for example /mnt/data/Music.

When you add an Amarok-on-Windows instance, this does not work anymore: It is not possible to have the exact same paths on a Windows system, for two reasons: 
1) because they use so-called drive letters
2) because the path separator is a backslash instead of a slash (the latter is currently not a problem, because even Windows instances use slashes internally, but once bug 195161 gets fixed by having backslashes in the database, instead of slashes, it will become a problem)

So while an example entry in the collection database (urls table), created by the Linux instance looks like this:
id 	deviceid 	rpath 	directory 	uniqueid
7638 	-1 	./mnt/data/Music/Madina Lake - (2007) - [Alternative Rock] - From Them, Through Us, To You/[12] Madina Lake - Morning Sadness.mp3 	602 	amarok-sqltrackuid://5f1300e27f2bbd51fef5b14722d2f966

... the same entry created by a Windows instance looks like that:
id 	deviceid 	rpath 	directory 	uniqueid
7638 	-1 	M:/Music/Madina Lake - (2007) - [Alternative Rock] - From Them, Through Us, To You/[12] Madina Lake - Morning Sadness.mp3 	1681 	amarok-sqltrackuid://5f1300e27f2bbd51fef5b14722d2f966

We need a way to make this OS-independent, so that it's possible to access the collection database by multiple Amarok instances on different OSes at the same time.

Reproducible: Always
