add support for 2.2 (new unified request protocol)

[rajatm]

Can the support for latest redis release 2.2.2 be added?

I have modified the code in ProtocolBase to support the new unified request protocol http://redis.io/topics/protocol by just replacing the method createRequest by following:

public Request createRequest(Command cmd, byte[]... args) throws ProviderException, IllegalArgumentException {

    ByteArrayOutputStream buffer = createRequestBufffer (cmd);

    try {
        int argsCount = 1;
        if(args != null) {
            argsCount += args.length;
        }
        buffer.write(COUNT_BYTE);
        buffer.write(Convert.toBytes(argsCount));
        buffer.write(CRLF);

        buffer.write(SIZE_BYTE);
        buffer.write(Convert.toBytes(cmd.bytes.length));
        buffer.write(CRLF);
        buffer.write(cmd.bytes);
        buffer.write(CRLF);

        for(int s=0; s<args.length; s++){
            buffer.write(SIZE_BYTE);
            buffer.write(Convert.toBytes(args[s].length));
            buffer.write(CRLF);
            buffer.write(args[s]);
            buffer.write(CRLF);
        }
    } catch (Exception e) {
        throw new ProviderException("Problem writing to the buffer" + e.getLocalizedMessage());
    }
    return createRequest(buffer);
}

As of now it seems to be working fine at least for Synch Connection. Please check and incorporate if fine.

Give the trunk another try. Its up to Redsi 2.2.4
