remove the error return value from wire.Frame.MinLength
...
No functional change expected.
The error was only non-nil if some required values for the STOP_WAITING
frame were not set. It should be sufficient to throw an error when
attempting to write an invalid STOP_WAITING frame.

This function was needed when we supported both Q039 (using big endian

refactor packet unpacking
...
This replaces version.UsesMaxDataFrame by versoin.UsesIETFFrameFormat.
That way, we can have two separate code paths in the unpacker to unpack
either gQUIC frames or IETF frames.

reject packets with version 0 sent by the client

Version 0 is an invalid version. For packets sent by the server, it is
used to identify the Version Negotiation Packet.

fix parsing of the Header type byte
...
In order to determine if a packet is a Version Negotiation Packet, it is
not sufficient to just look at bit 0x1. Other packet types also have
that bit set, e.g. the Retry packet (packet type 0x3). Instead, we have
to look at the last 3 bits. This fix will work as long as IETF QUIC
doesn't define more than 8 long header types.
