HAL backend for media:/

[Jérôme Lodewyck]

Hi,

 as some might have noticed, a Hardware Abstraction Layer backend for the new 
media kioslave has been written (in kdebase/kioslave/media/kdedmodule/). It 
is compiled if the following requirements are met :
- HAL >= 0.4
- DBus
- DBus-Qt bindings from CVS (not that usual...)

It is loaded at launch time instead of the standard fstab backend if HAL is 
reachable.

As for now, it mostly needs more testing, with all kind of media : cd/dvd/vcd, 
removable mass storage, gphoto2 camera. Alpha 1 is surely a great opportunity 
to test it !

There are a few bugs detected :
- the mimetype for directories under a device handled by audiocd:/ is flawed 
(a default icon appears instead of the usual directory icon). I could correct 
this by adding the line 
app_entry(e, KIO::UDS_MIME_TYPE, "inode/directory");
if the function static void app_dir(UDSEntry& e, const QString & n, size_t s)
from audiocd.cpp. I am not sure whether this is The Right Thing To Do. Perhaps 
the audiocd folks could be advisable ?

- for devices handled by gphoto2 : the tree view in konqueror cannot unfold 
the device subfolders with a "can't access parent directory" warning. This 
content can be opened though. I don't know where it comes from.

Hope some of you can test it,

Jérôme
