ALSA: OSS sequencer should be initialized after snd_seq_system_client_init
...
When build SND_SEQUENCER in kernel then OSS sequencer(alsa_seq_oss_init)
is initialized before System (snd_seq_system_client_init) which leads to
memory leak :

The correct order should be :
System (snd_seq_system_client_init) should be initialized before
OSS sequencer(alsa_seq_oss_init) which is equivalent to :
1. insmod sound/core/seq/snd-seq-device.ko
2. insmod sound/core/seq/snd-seq.ko
3. insmod sound/core/seq/snd-seq-midi-event.ko
4. insmod sound/core/seq/oss/snd-seq-oss.ko
Including sound/core/seq/oss/Makefile after other seq modules
fixes the ordering and memory leak.

Remove sequencer instrument layer from the tree.
This mechanism hasn't been used much with the actual devices. The only
reasonable user was OPL3 loader, and now it was rewritten to use hwdep
instead. So, let's remove the rest of rotten codes.

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!
