6f4bc52250 h2: Pad RST_STREAM frames
Clients sending too many RST_STREAM is an irregular behavior.

Hack in a preceding END_STREAM DATA frame padded towards [48, 72]
before RST_STREAM so that the TLS record looks like a HEADERS frame.

The server often replies to this with a WINDOW_UPDATE because padding
is accounted in flow control. Whether this constitudes a new irregular
behavior is still unclear.

82d2420d08 Raise initial padding number to 8
Protect initial handshake lengths.

Common client initial sequence:

- TLS: ClientHello
- TLS: ChangeCipherSpec, Finished
- H2: Magic, SETTINGS, WINDOW_UPDATE
- H2: HEADERS: GET
- H2: SETTINGS ACK

Common server initial sequence:

- TLS: ServerHello, ChangeCipherSpec, ...
- TLS: Certificate, ...
- H2: SETTINGS
- H2: WINDOW_UPDATE
- H2: SETTINGS ACK
- H2: HEADERS: 200 OK

4d627002e5 Negotiate padding capability automatically
Client: On the first connection does a full Open and detects if the
server supports padding by checking for "Padding" header in the
response. Applies padding if the server does. In the following
connections it's back to Fast Open.

Server: Detects if the client supports padding by checking for "Padding"
header in the CONNECT request. Applies padding if the client does.

Both client and server always send "Padding" headers to somewhat protect
the request and response headers' packet lengths, even if the other side
may not acknowledge padding negotiation, either due to old version or
"Padding" headers being dropped by the frontend.

The manual option --padding is removed.

62e5e9cfff Handle payload data immediately after HTTP headers
In HttpProxySocket there can be data immediately after HTTP headers,
as in the case of fast HTTP CONNECT.

Instead of reporting an error, handle this case by returning
the data after HTTP headers in the next Read() call.
