      * replacer: evaluate format once and improve perf by ~3x

This improves the performance of logging by almost 3x and reduces memory
usage by ~8x.

* replacer: code review comments

* bufPool: document why we use a pointer to a slice
* parseFormat: fix confusing comment
* TestParseFormat_Nodes: rename to TestParseFormatNodes

* replacer: use a value for bufPool instead of a pointer

* replacer: remove comment

* replacer: replace labels with knownLabels

The previous slice of label names is no longer needed.

      Fix log plugin benchmark and slightly improve performance (#3004) · 21e9c604
      Charlie Vieth authored 
      * log: use ioutil.Discard as write buffer in benchmark

Using a buffer gives unrealistic stats and consumes a large amount of
memory.

* log: lazily check if a msg should be logged

* log: improve variable name

Change 'ok' to the more descriptive 'shouldLog'.

* log: code comments: don't reuse variable

      plugin/file: load secondary zones lazily on startup (#2944) · 3a0c7c61
      Miek Gieben authored 
      This fixes a long standing bug:
fixes: #1609

Load secondary zones in a go-routine; this required another mutex to
protect some fields; I think those were needded anyway because a
transfer can also happen when we're running; we just didn't have a test
for that situation.

The test had to be changed to wait for the transfer to happen at this is
async now.
