CL 720820 changed net/http to use a 307 Temporary Redirect instead of
a 301 Moved Permanently when performing an automatic redirect under
some circumstances. Update tests in the webdav package to be agnostic
on the exact redirect status code.

Permit net/http to create new HTTP/2 client connections.

We do this by adding a NewClientConn method to the type the HTTP/2 client
registers with net/http.Transport.RegisterProtocol, which creates a
persistent connection from a net.Conn.

No tests in this CL. Tests will be in net/http, and will cover
both the HTTP/1 and HTTP/2 paths for NewClientConn.

When sending a RST_STREAM for a canceled request, we sometimes send
a PING frame along with the reset to confirm that the server is responsive
and has received the reset.

Sending too many PINGs trips denial-of-service detection on some servers,
causing them to close a connection with an ENHANCE_YOUR_CALM error.

Do not send a PING frame along with an RST_STREAM if the connection
has displayed signs of life since the canceled request began.
Specifically, if we've received any stream-related frames since the
request was sent, assume the server is responsive and do not send a PING.

We still send a PING if a request is canceled and no stream-related
frames have been received from the server since the request was first
sent.

This commit updates the RenderEvents function by moving the read
lock for event families so that it happens before checking the
length of event families and by that fixing a data race problem.
