FS#5623 - add a directory walker functoin to reduce code reuse

this patch adds a directory walker function to reduce lots of code reuse (the same sort of function apears about a half-dozen times in playlist.c alone.. )

this patch also updates the stats plugin to use the dir walker.

edit: may as well mention i did it iterativly in the ope its a bit faster on the player than recursive.

very out of date and probably not worth adding anyway

ok, realised the recurse variable was completly unnescacery

new version, this one includes the needed tchanges to playlist.c to use the dirwalker.

im not 100% sure why, but get_next_directory doesnt work exactly as it used to now, but that can be figured out later.
also, i was hopeing it would drop the filesize a bit, but apparently not..

but, imo its worth the extra 280bytes to make it easier later.

synced to cvs,
also changed some minor bits so its hopefully faster and smaller… tested on my h300 and it works perfectly

Currently I didn’t test it - but it seems to be a very good idea for me!
I had a look at the patch and it makes the code much more understandable
which is IMHO always a good idea :-)

I also like the idea of a fileutil.c -
I assume there are a lot more currently internally used functions/code parts
which which do something for or with files and could be moved to general usage.
