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.
