[DeviceDriver] correct rx_fifo init size error

mv device ctl cmd macros from serial.h to rtdef.h

[BSP]stm32f10x: Fix gpio driver for 144pins and 64pins

[BSP]stm32f10x: Add gpio driver for pin driver frame

[DeviceIPC] Fixed completion.c

fix: completion wait after, maybe can't clean the flag.

[BSP] Correct pin register name problems

building: PrepareBuilding forgot to declare BuildOptions as global

The global variables in the building.py are totally a pile of shit.

Add bsp_directory for PrepareModuleBuilding function and module building environment can parse rtconfig.h too.

[bsp] add uart4 driver for stm32f10x bsp.

[BSP] TM4C129X Fix bugs and errors.

Port Nanopb[zlib license] for protocal encode/decode

format. It is targeted at 32 bit microcontrollers, but is also fit for
other embedded systems with tight (2-10 kB ROM, <1 kB RAM) memory
constraints.(http://koti.kapsi.fi/jpa/nanopb/)

How to use the example:
	1. move examples/nanopb to bsp/xxxx/
	2. enable macro RT_USING_NANOPB in rtconfig.h
	3. regenerate the project file (scons --target=xxxx)
	4. rebuild the project

2. [BSP] TM4C129x : According to LunchPad, change device id from TM4C1294XCNZAD   to TM4C1294NCPDT
