* [add] the function realization of signal for posix.
* [update] the posix support for armclang.
* [add] the new macro "RT_USING_POSIX_TIMER".
* [modify] select "RT_USING_SOFT_TIMER" when use posix'timer.
* [bug] optimize the logic for the "time_xxx" functions.
* [modify] use "RT_USING_POSIX_TIMER" to protect the macro definition.
* [modify] error code when except happened.
* [delete] the "environ" is useless at this time.

- Backward compatible with existing function-pointer based hooking method
- Using RT_USING_HOOK as an on/off switch
- Introducing a new low-overhead macro-based hooking method

[kernel] Add __attribute__(...) for rt_kprintf() to let the compiler check the format string parameters

Tested in the following environment：
1. Keil uVersion：Arm Compiler v5.06、v6.7、v6.16  
2. Atollic TrueSTUDIO for STM32：GNU v6.3.1  
3. Code Composer Studio：TI Compiler v20.2.2.LTS、GNU v7.2.1

1. Add RTGRAPHIC_CTRL_PAN_DISPLAY and RTGRAPHIC_CTRL_WAIT_VSYNC control command.
2. Add calibration data of 480x272 ADC touching.
3. Add 480x272 LCD panel menu option and driver.
4. Update lv_conf.h.
