function `rt_pin_write` is invoked by  function `can_bus_hook`, and it should to be initialized by gpio.c.
but gpio.c was not added in SConscript

enum CANBAUD was changed in components/drivers/include/drivers/can.h ,
which causes array index out of bound in bsp/stm32f10x/drivers/bxcan.c

temporarily remove RT_CAN_USING_BUS_HOOK, because there are some bugs in
bsp/stm32f10x/applications/canapp.c  function can_bus_hook

finsh_set_device is not needed since version 1.2.0

temporarily disable canapp initialization.

2.add change log

rename bsp/stm32f10x/drivers/rtc.h to stm32f10x/drivers/stm32f1_rtc.h

remove set_date,set_time function.
