* Do not shell-quote strings in the metadata token expansion function
  * This fixes https://github.com/xiph/ezstream/issues/6
* Expand all tokens at the same time in a way that ensures metadata
  is not additional input to expansion
* Simplify several functions and remove unused functionality

* Move -m and -n command line options into the config file
* Restructure configuration file:
  - Group into "server", "stream", "media", "metadata", "decoders", and
    "encoders"
  - Untangle decoder and encoder:
    o Decoders match on file extensions and convert to a canonical "internal"
      format
    o Encoders create one of the supported stream formats, potentially using
      different parameters (like bitrate)
  - Consistently specify stream format
  - Enable reencoding by selecting an encoder
* Architecturally separate configuration file storage from parsing
  - Allows for different configuration back-ends in the future, like
    YAML, SQL, REST API, ...
* Support roll-back in case of error on (re)load
* Anticipate HTTPS support

This makes ezstream log via syslog and stderr. The "real-time status
line" remains unaffected.
While here, make the output more concise and consistent.

Why yes, it /is/ KNF!

I do not plan to ever keep that up to date in case they move again.
If you need a copy of the GPL, use the Internet or read COPYING.

and I concur.

* Add 'charset=UTF-8' to the metadata update query arguments. The current
  release of Icecast will ignore it, and the next one will know how to handle
  it (karl@ is still working on it at this point, but previous diffs worked
  as advertised.)
* If no metadata format string is available and we have both an artist and
  a title, use the artist/title way of updating instead of the generic "song"
  interface.
