networking: socket to/from file descriptor

 o Move rtems_bsdnet_fdToSocket() and rtems_bsdnet_makeFdForSocket() to
   "cpukit/libnetworking/rtems/rtems_syscall.c".
 o The rtems_bsdnet_makeFdForSocket() function is now static.
 o Check in rtems_bsdnet_fdToSocket() function that the file descriptor
   uses the socket handlers, otherwise an error status will be returned
   and errno set to ENOTSOCK.
 o New test libtests/syscall01.
