Some lib_aci functions should use const pointers I think

[Fred Roeber]

I'm using the Arduino SDK but I don't think that should matter for this comment. I think a small change to some of the lib_aci functions would make it easier to use them. Functions that take a buffer of data and don't change the buffer should declare the buffer pointer "const". That way we can pass static/const buffers in without having to add kludge casts to the calls.

In particular I think the following parameters should be const:

• value parameter to lib_aci_set_local_data
• value parameter to lib_aci_send_data
• dynamic_data parameter to lib_aci_write_dynamic_data
• key parameter to lib_aci_set_key
• message_data parameter to lib_aci_echo_msg

We will consider this and there is an outstanding pull request for a similar change in github.
