Moved to subr_bufq.c.

What copyright do I have to put in it? I'm not sure.

Can you please explain why is it broken? I would like to fix it
but I don't know what's the problem. 

I tested it copying large files (>500MB) and it didn't crash (without
softdep). With softdep enabled I get the panic
"softdep_deallocate_dependencies: dangling deps".

I removed completely the struct disk_sched and replaced it with
a pointer to char, is this ok now?

Now only four kernel files are modified:

	* sys/kern/subr_disk.c (bufq_* funcs moved to subr_bufq.c)
	* sys/dkio.h (for the ioctls)
	* sys/conf/files (to add subr_bufq.c)
	* and the driver (in that case wd.c)
