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.

Instead of a comment string, store the device type in the snd_minor
structure. This makes snd_minor more flexible, and has the nice side
effect that we don't need anymore to create a separate snd_minor
template for registering a device but can pass the file_operations
directly to snd_register_device().

Modules: ALSA Core,Control Midlevel,/oss/Makefile
Remove the centralized PM control in the sound core.
Each driver is responsible to get callbacks from bus/driver now.
SND_GENERIC_DRIVER is removed together with this action.

Remove snd_runtime_check() macro.
This macro worsens the readability of codes. They should be either
normal if() or removable asserts.
Also, the assert displays stack-dump, instead of only the last caller
pointer.

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!
