journald now counts received log messages by priority and by transport in $RUNTIME_DIRECTORY/counters, which it keeps mapped for its whole runtime. The counters hence survive restarts of journald, but are reset on reboot. Messages are counted in each transport right after their priority is known, i.e. before any filtering (LogLevelMax=, LogFilterPatterns=, MaxLevelStore=, Storage=none) or rate limiting is applied. Kernel messages are only counted after the kernel seqnum check, so that messages seen before a restart are not counted twice. journald's own messages are not counted. This introduces a JournalTransport enum for the transports we receive messages on, whose string names match the _TRANSPORT= field.
