Kai Liu / Mbed 2 deprecated CC1101_Transceiver

Codebase from CC1101_Transceiver, ported to LPC1114/LPC824/STM32F103 and other micros, will be merged with panStamp project to replace AVR/MSP.

Dependencies:   mbed

allankliu 2:0e79d58be0f6 5 Changes:
allankliu 2:0e79d58be0f6 6 - Optimization for Low Power Consumption Operations
allankliu 2:0e79d58be0f6 7 - GD0 as external interrupt, to bring MCU from deep sleep mode.
allankliu 2:0e79d58be0f6 8 - GPIO setup
allankliu 2:0e79d58be0f6 9 - Clock setup
allankliu 2:0e79d58be0f6 10 - Event driven design
allankliu 2:0e79d58be0f6 11 - ALOHA transceiver for channel access with RTS/CTS/ACK
allankliu 2:0e79d58be0f6 12 - S-MAC
allankliu 2:0e79d58be0f6 13 - Cloned high level designs from SimpliciTI.
allankliu 2:0e79d58be0f6 14 - New CircularBuffer from mbed 5
allankliu 2:0e79d58be0f6 15
allankliu 2:0e79d58be0f6 16 Status:
allankliu 2:0e79d58be0f6 17 - CC1101 SPI access to regsiters from PARTNUM/VERSION to RCCTRL0 not stable
allankliu 2:0e79d58be0f6 18 - PARTNUM ranges from 0x00/0xFF
allankliu 2:0e79d58be0f6 19 - VERSION ranges from 0x0F/0x1F/0x4F
