markers: create DEFINE_MARKER and GET_MARKER (new API)
Impact: new API.
Allow markers to be used only for declaration, without function call
associated. Useful to create specialized probes.
The problem we had is that two function calls were required when one
wanted to put a marker in a tracepoint probe. Now the marker can be used
simply for trace data type declaration, leaving the trace write work
within the tracepoint probe without any additional function call.
