Add target_freebsd_thr_param, target_freebsd_rtprio,
new_freebsd_thread_info_t, TARGET_UMTX_OP_* opcodes, umutex/urwlock
flags, and target_freebsd_acl structures to syscall_defs.h. Add forward
declarations for os-time.c, os-socket.c, os-thread.c, and os-extattr.c
functions to qemu-os.h. Add thread and umtx function declarations to
qemu.h.
