- journald: when dropping msgs due to ratelimit make sure to write
"dropped %u messages" not only when we are about to print the next
message that works, but alraedy after a short tiemout
+ - ratelimit should be configurable by message severity and by service/source
- check if we can make journalctl by default use --follow mode inside of less if called without args?
- maybe add API to send pairs of iovecs via sd_journal_send
- journal: when writing journal auto-rotate if time jumps backwards
