Release comments:

This release includes two major API changes for chunkd:

	1) keys are now fully opaque binary BLOBs

	2) an upper-level namespace, "tables", was added,
	   to permit separate key/value namespaces without
	   having to provision a new chunkd instance

We are getting close to version 1.0 for chunkd.  epoll I/O engine, 
request logging, minimal API docs and a usable password lookup (database 
or SASL) are goals for release 1.0, and should be easy to attain.


Release notes for version 0.5:

- Protocol/API: Add an upper-level key/value namespace ("tables")
- Protocol/API: each object now indexed by opaque binary keys <= 1K in size
- Protocol/API: new option to immediately sync data to disk
- Protocol/API: introduce login sequence, greatly shrinking per-message size
- API: change error code symbols to avoid clashes with other projects
- chunkd: automatic selection of TCP listen port
- chunkd: drop libevent use
- Add new 'chcli' command line client
