protocols: refactor protocol logging to a macro (#7324)

this avoids the usage of the unique_ptr PROTO::protocol before it has
been constructed incase one wants to log something inside the
constructor itself, move the logging to macros and print file:linenumber
on ERR,CRIT,WARN and classname on the rest of the levels.
