ALSA: emu10k1: rework copyright statements

- Remove the "log-like" parts, following the same logic as the previous
commit
- Unify format
- Add missing major contributors, including myself
- Sort entries in order of first contribution (Creative comes last for
optical reasons; they don't appear to have directly contributed
anyway)

ALSA: emu10k1: clean up driver status comments

Empty BUGS and TODO sections don't really help anyone, so remove them.

Version information is chronically outdated, and not really useful in a
git world anyway, so remove it as well.

Also remove duplicated (and outdated, of course) status section from
p16v.h (the one in p16v.c is in better shape).

ALSA: emu10k1: revamp playback voice allocator

Instead of separate voices, we now allocate non-interleaved channels,
which may in turn contain two interleaved voices each. The higher-level
code keeps only one pointer per channel. The channels are not allocated
in one block any more, as there is no reason to do that. As a
consequence of that, and because it is cleaner regardless, we now let
the allocator store these pointers at a specified location, rather than
returning only the first one and having the calling code deduce the
remaining ones.

ALSA: emu10k1: make snd_emu10k1_voice_alloc() assign voices' epcm

The voice allocator clearly knows about the field (it resets it), so
it's more consistent (and leads to less duplicated code) to have the
constructor take it as a parameter.

ALSA: emu10k1: make freeing untouched playback voices cheap

This allows us to drop the code that tries to preserve already allocated
voices upon repeated hw_param callback invocations. Getting it right for
multi-channel voices would otherwise get a bit hairy.

ALSA: emu10k1: improve voice status display in /proc

Eliminate the MIDI type, as there is no such thing - the MPU401 port
doesn't have anything to do with voices.

For clarity, differentiate between regular and extra voices.

Don't atomize the enum into bits in the table display.

Simplify/optimize the storage.

The subsequent allocation may still fail after freeing some voices, so
we shouldn't leave them in their programmed state.

sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed

These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition. Previously,
they got it via the implicit module.h inclusion.

[ALSA] Remove sound/driver.h

This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.

Linux-2.6.12-rc2

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!
