Necko does not allow for a CONNECT only request to happen. This adds a flag
to signal an http channel should only CONNECT if proxied. This flag can only be
set if an HTTPUpgrade handler has been assigned. As proposed by rfc7639, an
alpn header will be included in the CONNECT request. Its value is determined by
the upgrade protocol passed to HTTPUpgrade.
The flag is added as part of nsIHttpChannelInternal because it is dependent on
HTTPUpgrade. It exists as a capability flag since the channel's transaction
needs to know to complete after a successful CONNECT. Also the transaction's
connection needs to know to stop writing transaction data after it CONNECTs or
if there's no proxy, and to not tell the transaction to reset.
If an nsHttpChannel has this flag set then the upgrade handler will receive the
socket after the CONNECT succeeds without doing tls if https.
In order to support xpcshell-test for this change, nsHttpConnectionMgr does a
little check to see if HTTPUpgrade callback is in JavaScript. If it is then
the callback is invoked on the main thread.
