Bug #180965: Mac gets PR_IO_PENDING_ERROR.  In
SendReceiveStream and SendReceiveDgram, make
sure that we set the io_pending flag of the current
thread to PR_FALSE before we return.
In gethostbyname(), just store the OS error code in
me->md.osErrCode.  Do not call macsock_map_error()
to map to NSPR error code.
