unicorn 0.98.0

Deployments that suspend or hibernate servers should no longer
have workers killed off (and restarted) upon resuming.

For Linux users of {raindrops}[http://raindrops.bogomips.org/]
(v0.2.0+) configuration is easier as raindrops can now
automatically detect the active listeners on the server
via the new Unicorn.listener_names singleton method.

For the pedantic, chunked request bodies without trailers are no
longer allowed to omit the final CRLF.  This shouldn't affect
any real and RFC-compliant clients out there.  Chunked requests
with trailers have always worked and continue to work the same
way.

The rest are mostly small internal cleanups and documentation
fixes.  See the commit logs for full details.
