stm class: Propagate source type to protocols
Pass stm source type via stm_write() to allow different handling on protocol level. The measure above should allow protocol level encoder to differentiate and accordingly pack the messages. As an example SyS-T might get use of ftrace message ID's and instead of applying regular header, pack them as SyS-T catalog or SyS-T Structured Binary Data message to allow proper decoding on the other side.
