(issue #133, issue #167).

- Clean up and refactor code in several places.
- [API] Rename "0-RTT" to "session resumption." In IETF QUIC, "0-RTT"
always refers to early data, meaning a request that the server can
reply to in the very first return flight. A more appropriate name
for what we support on the client site is "session resumption," which
is standard TLS terminology. Later, when we add support for 0-RTT
(early data), we can use the 0-RTT terminology again, this time in
proper context.

draft.

UDP payload, not QUIC packet.

- Code cleanup; minor fixes.
- [HTTP3] Verify number of bytes in incoming DATA frames against
content-length.
- [HTTP3] Stop issuing streams credits if peer stops opening QPACK
decoder window. This addresses a potential attack whereby client
can cause the server to keep allocating memory. See Security
Considerations in the QPACK draft.

- Log number of pacer calls at DEBUG, rather than NOTICE, level.
- [BUGFIX] Q044: don't encode packet number in 6 bytes. Six-byte
packet number encoding does not exist in Q044. This fixes a
regression introduced in '[BUGFIX] Buffered packets can contain
ACK frames' -- we need to keep QUIC version in mind when selecting
the longest possible packet number encoding used for the buffered
packet that carries the ACK.
- [BUGFIX] Do not increase CWND when timeout occurs.
- http_client: support setting handshake timeout on command line.
Use -o handshake_to=timeout.
- http_client: use -k to connect UDP socket to pick up ICMP errors.
- http_client: allow pathless mode, when only handshake is performed
without issuing any requests. This can be done by simply not
specifying a -p flag on the command line.

information; it can be supplied to a subsequent connect() call.
