Pack parameters of nsh_execute() as struct nsh_exec_param_s

Browse Source 
1. Input redirect flags currently is hardcode, passing by arguments maybe better.
2. Only support redirect to path_name, redirect to fd is needed for pipeline.

Test
  1. Redirect in
    cat < /etc/init.d/rc.sysinit

  2. Redirect with FIFO
    mkfifo /dev/testfifo
    cat /dev/testfifo &
    ls > /dev/testfifo

  3. NSH Params
    set name `uname`
    echo $name
