sound: Remove OSSlib stuff from linux/soundcard.h 



Removed OSSlib stuff from linux/soundcard.h to fix the warnings for
'make headers_check'.

This patch breaks building against OSSlib with the kernel headers
instead of its own headers. It should still work with any
version of the library from the 2003 onwards which provide
their own headers for the latest interface.

 *	Some convenience macros to simplify programming of the

 *	/dev/sequencer interface

 *

 *	These macros define the API which should be used when possible.

 *	This is a legacy interface for applications written against

 *	the OSSlib-3.8 style interface. It is no longer possible

 *	to actually link against OSSlib with this header, but we

 *	still provide these macros for programs using them.

 *

 *	If you want to use OSSlib, it is recommended that you get

 *	the GPL version of OSS-4.x and build against that version

 *	of the header.

 *

 *	We redefine the extern keyword so that make headers_check

 *	does not complain about SEQ_USE_EXTBUF.
