- implement baseic stubs for capget, capset, prctl PR_GET_KEEPCAPS and prctl PR_SET_KEEPCAPS. - add SCM_CREDS support to sendmsg and recvmsg - modify sendmsg to ignore control messages if not using UNIX domain sockets This should allow linux pulse audio daemon and client work on FreeBSD and interoperate with native counter-parts modulo the differences in pulseaudio versions.
