Like the previous patch, this one embeds the device object into hwdep
object. For a proper object lifecycle, it's freed in the release
callback.
This also allows us to create sysfs entries via passing to the groups
field of the device without explicit function calls. Since each
driver can see the device and touch its groups field directly, we
don't need to delegate in hwdep core any longer. So, remove the
groups field from snd_hwdep, and let the user (in this case only
hda_hwdep.c) modify the device groups.

Just like PCM, allow hwdep to be assigned to a different parent device
than the card. It'll be used for the HD-audio codec device in the
later patches.

Instead of calling each time device_create_file(), create the groups
of sysfs attribute files at once in a normal way. Add a new helper
function, snd_get_device(), to return the associated device object,
so that we can handle the sysfs addition locally.
Since the sysfs file addition is done differently now,
snd_add_device_sysfs_file() helper function is removed.

The last argument, name, of snd_oss_register_device() is nowhere
referred in the function in the current code. Let's drop it.

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.

Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.
This makes the device type modules independent of the minor number
encoding.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
