0.5.0

Package collectd.org/config

• New package to represent collectd configurations.
• The Block type corresponds to oconfig_item_t, the Value type corresponds to oconfig_value_t.
• Block.Unmarshal maps a config.Block hierarchy to a Go type.
• Block.MarshalText produces a text output that could be parsed by collectd as a config file.
• The Port type represents a port number in the configuration. It demonstrates how to override the default unmarshaling rules to implement specialized behavior, such as range checking.

Package collectd.org/plugin

• Configuration callbacks, i.e. types implementing the Configurer interface, have been added. They are registered with RegisterConfig. Thanks to @alowde!
• The new LogWriter type implements an io.Writer on top of collectd's logging infrastructure. This allows, for example, to create a log.Logger backed by collectd.
