The check still has to require the packet to be at least 4 bytes long, 
so that it can check that the packet begins with "YMSG".

I changed it to use "tvb_memeql()", which returns -1 rather than 
throwing an exception, if there aren't enough bytes in the packet to 
match the value passed in.

Also, it (3) changes the length of the "ymsg.version" field to 2 bytes 
- but it still increases the offset by 4 bytes; what are the two bytes 
following the version field?
