IETF CONNECTION CLOSE code is varint encoded

In the recent (-22) version of the IETF QUIC Internet Draft, the
encoding of the close code in the Connection Close frames was changed
from uint16_t to varint62.

NOTE WELL, this just changes the serialization of the code. The error
code is stored as a uint16_t. A separate CL will change the base type
for the Transport Error Code and Application Error Code.

gfe-relnote: N/A is IETF QUIC/v99 code only.
