linux compat: improve and fix sendmsg/recvmsg compatibility
- 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.
