This commit introduces SocketCAN support for NuttX. New functions
socketCAN_open(char * dev)andsocketCAN_saveMsg(struct can_frame m)were added to support different open proccess and different NuttX structure of message, the overall princip remains the same (functionscanOpenTH(char * dev)andsendMsg(uint16_t ID, uint8_t DATA[], int len)are called from block´s source code). Filecanopen.cnow can support both characteristic device dev/can0 and socketcan.There are also few unused functions like
rcvMsg(uint8_t DATA[], int timeout),rcvMsgCob(int cob, uint8_t DATA[], int timeout)andcanOpen(char * dev). I am not sure whether they should be removed as they do not support real time receive or whether they can have some usage.SocketCAN communication was tested on existing blocks.
