Summary:
Allow server to accept session tickets with additional paramters that won't be used.
A subset of servers can include additional transport parameters in the session ticket that are only useful to them. This allows other servers to still use the ticket as long as it has the fields they expect, ignoring any additional parameters.

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.
