Reimplement OSS audio handling in pkgsrc. Add two new files:

	oss.buildlink3.mk
	oss.builtin.mk

that work like modern buildlink3.mk and builtin.mk files do.  We no
longer support audio/oss (which will be removed shortly).  Mark
ossaudio.buildlink3.mk for deprecation after all references to it
have been replaced with "oss.buildlink3.mk" in package Makefiles.
