Summary:
This eliminatees some tech debt by completely removing the notion of version from the core transport parameters structure and the app token for zero rtt.
Note that for the draft-27 changes we will need to temporarily re-introduce it, but to a different layer (the extension encoding itself).

Summary:
Draft-22 onwards uses two one byte length fields to encode connection ID length instead of one one byte length field.
To support this without disrupting existing clients we need to make our parsing version dependent. This diff accomplishes it by special casing the existing Facebook client QUIC version (0xfaceb000), and changing the default Facebook client version going forward to 0xfaceb001.
Note that this diff also changes the behavior of the ticket transport parameters. When we changed from draft-18 to draft-19 transport parameters I apparently forgot to update the ticket transport parameters to the new format.

Summary: Additionally this fails 0-rtt if the idle timeout changes. This avoids the problem where an old client sends an invalid idle timeout transport param.
