Enhanced system logging daemon (stardate plugin)

syslog-ng is an enhanced log daemon, supporting a wide range of input and output methods: syslog, unstructured text, message queues, databases (SQL and NoSQL alike) and more.

Key features:

 * receive and send RFC3164 and RFC5424 style syslog messages
 * work with any kind of unstructured data
 * receive and send JSON formatted messages
 * classify and structure logs with builtin parsers (csv-parser(),
   db-parser(), etc.)
 * normalize, crunch and process logs as they flow through the system
 * hand on messages for further processing using message queues (like
   AMQP), files or databases (like PostgreSQL or MongoDB).

This package provides a stardate-like date formatting module which formats the date with months and days as fragments of the year. For example, it formats 2017.06.15 as something like 2017.500.
