  Log:
  Introduce the function iovec_copyin() and it's friend iovec_free().
  These remove a great deal of duplicate code in the syscall functions.
  For those who like numbers, this patch uses iovec_copyin() four times
  in uipc_syscalls.c, two times in linux_socket.c and two times in
  43bsd_socket.c.  Would somebody please comment on the inclusion of
  sys/malloc.h in sys/uio.h?
  
  Remove sockargs() which was used once in the svr4 emulation code.  It
  is replaced with a small piece of code that gets an mbuf and copyin()'s
  to it's data region.
  
  Remove the osendfile() syscall which was inapropriately named and placed
  in the COMPAT_43 code where it doesn't belong.
  
  Split the socket(), shutdown() and sendfile() syscalls.  All of the
  syscalls in kern/uipc_syscalls.c are now split.
  
  Prevent a panic due to m_freem()'ing a dangling pointer in recvmsg(),
  orecvmsg(), linux_recvmsg().
  
  This patch completely removes COMPAT_43 from kern/uipc_syscalls.c.
