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.
