** Revision: 1.1
**
** Lowest Common Denominator Protocol Buffers Client
**   - no ENUM (protobuffs_erlang does not support)
**
** Protocol
**
**   The protocol encodes requests and responses as protocol buffer messages.
**   Each request message results in one or more response messages.
**   As message type and length are not encoded by PB they are sent
**   on the wire as
**
**     <length:32>  <msg_code:8> <pbmsg>
**
**     length is the length of msg_code (1 byte) plus the message length
**     in bytes encoded in network order (big endian)
**
**     msg_code indicates what is encoded as pbmsg
**
**     pbmsg is the encoded protocol buffer message
**
**   On connect, the client can make requests and will receive responses.
**   For each request message there is a corresponding response message,
**   or the server will respond with an error message if something has
**   gone wrong.
**
**   The client should be prepared to handle messages without any pbmsg
**   (i.e. length==1) for requests like ping or a put without return_body set.
