Maxavro now supports reading records with the zlib deflate
algorithm.
With this change, each data block is read into memory in one IO
operation. This allows the library to decompress the data block if
necessary.
The avrorouter does not yet use compression when writing the records.
All modules now declare a name for the module. This is name is added as a
prefix to all messages logged by a module. The prefix should help
determine which part of the system logs a message.
