Use uint8_t/uint32_t etc to replace u_char/u_long etc;
Use getchar for shell input.

    a. 恢复对finsh.h和shell.c的修改；（若需要在Andes AE210P里使用Finsh，请参照bsp/AE210P/readme/readme做修改）

[2] 基于AE210P EVB板；

When MSH enabled, the prompt will change at the two shells. So we should
use dynamic prompt when FINSH_USING_MSH defined.

1. rt_console_get_device should be call to set shell device only when it is null, or it will make finsh_set_device useless.
2. RT_USING_CONSOLE can be disabled in bsp/rtconfig.h

We split the history handling form the key handling. So we could handle
the direction key even if the history is disabled. As a "side effect", I
also remove the unnecessary "use_history" bit.

Because the device could still remain opened when closed by finsh, the
old rx_indicate is useless for finsh. Some buggy driver will still
generate rx_indicate even after the device has been closed. So FinSh
should unregister the rx_indicate when releasing the old device.
