OTA Agent initialization function.

OtaErr_t OTA_Init( OtaAppBuffer_t * pOtaBuffer,
                   OtaInterfaces_t * pOtaInterfaces,
                   const uint8_t * pThingName,
                   OtaAppCallback_t OtaAppCallback );

Initialize the OTA engine by starting the OTA Agent ("OTA Task") in the system. This function must be called with the connection client context before calling OTA_CheckForUpdate. Only one OTA Agent may exist.

Parameters

[in]	pOtaBuffer	Buffers used by the agent to store different params.
[in]	pOtaInterfaces	A pointer to the OS context.
[in]	pThingName	A pointer to a C string holding the Thing name.
[in]	OtaAppCallback	Static callback function for when an OTA job is complete. This function will have input of the state of the OTA image after download and during self-test.

Returns: OtaErr_t The state of the OTA Agent upon return from the OtaState_t enum. If the agent was successfully initialized and ready to operate, the state will be OtaAgentStateReady. Otherwise, it will be one of the other OtaState_t enum values.
