This uses our existing http/2 CONNECT infrastructure (modified) to
enable the new extended CONNECT form defined by 8441, and pretend for
the websocket's sake that an http/2 stream is actually a socket. From
the websocket's point of view, this is relatively non-invasive - a few
things have changed (http response code, absence of some headers) versus
http/1.1 websockets, but for the most part, the websocket code doesn't
care.

When PR_Read/PR_White returns -1, we have to use ErrorAccordingToNSPR to get the error code. We need to close the transaction if the real error happens.

The inner window id here is used to log the error message to the right web console.
So, top level content window id should work properly if we can't get the inner window id directly from the request.

Previously, we were sending INTERNAL_ERROR, but that's not really true. Firefox hasn't hit an error, we're just shutting down. It makes more sense to tell the peer we're not messed up, just going away nicely.

In certain cases (such as the case from bug 1050329, where a server claims to speak h2, but really doesn't), we will end up trying every connection to that server as h2 before falling back to http/1.1. Once we know a server is very badly behaved, it doesn't make sense to keep trying h2 (at least for the current browsing session). This adds an in-memory blacklist of origins & conninfos to not try h2 on, so we don't waste round trips trying h2, failing, and then dialing back with http/1.1 except for the first connection to an origin.

This is kind of like the previous patch (where we had a not-very-friendly user experience shutting down misbehaving h2 sessions), but in this case the server has proven to us that it can speak a minimum of h2, so we don't want to just fallback. Instead, when we send a GOAWAY frame because we have detected some error on the part of the server, if it's a top-level page load, we'll show an error page explaining that the server spoke bad http/2, and the site admin(s) need to be contacted. We already did this for INADEQUATE_SECURITY (which is its own special case still), but that didn't cover all the cases.

Previously, we would just let these fail. But, when a peer claims to speak h2 via ALPN, and then plainly doesn't speak h2 (by not doing the opening handshake properly), we should re-try any transactions dispatched to that session using http/1.1 only. No use in giving the user a horrible experience. We will also collect telemetry on how often we have sessions where this happens, so we can see how big of a problem this is (and thus if we need to do any kind of outreach).

Previously this was a macro, but in later patches in this series, I want to make the macro a bit smarter. There's no particular need to have it as a macro (and macros that return from functions are often considered no-nos), so this makes it a method on the session, instead.

In the current code there are 3 main issues:
1. nsFileStream is not really thread-safe. There is nothing to protect the
internal members and we see crashes.
2. nsPipeInputStream doesn't implement ::Seek() method and that caused issues
in devtools when a nsHttpChannel sends POST data using a pipe. In order to fix
this, bug 1494176 added a check in nsHttpChannel: if the stream doesn't
implement ::Seek(), let's clone it. This was an hack around nsPipeInputStream,
and it's bad.
3. When nsHttpChannel sends POST data using a file stream, nsFileStream does
I/O on main-thread because of the issue 2. Plus, ::Seek() is called on the
main-thread causing issue 1.
Note that nsPipeInputStream implements only ::Tell(), of the nsISeekableStream
methods. It doesn't implement ::Seek() and it doesn't implement ::SetEOF().
With this patch I want to fix point 2 and point 3 (and consequentially issue 1
- but we need a separate fix for it - follow up). The patch does:
1. it splits nsISeekableStream in 2 interfaces: nsITellableStream and
nsISeekableStream.
2. nsPipeInputStream implements only nsITellableStream. Doing this, we don't
need the ::Seek() check for point 2 in nsHttpChannel: a simple QI check is
enough.
3. Because we don't call ::Seek() in nsHttpChannel, nsFileStream doesn't do I/O
on the main-thread, and we don't crash doing so.
In trying to use fetch with alt-data, we sometimes want the benefit of using alt-data but the JS consumer actually needs to use the original HTTP response from the server.
To get around this problem, we introduce a new API - nsICacheInfoChannel.getOriginalInputStream(nsIInputStreamReceiver) that asyncly receives the input stream containing the HTTP response in the cache entry.

This patch changes the way we set and handle the preferred alternate data type.
It is no longer just one choice, but a set of preferences, each conditional
on the contentType of the resource.
For example:
var cc = chan.QueryInterface(Ci.nsICacheInfoChannel);
cc.preferAlternativeDataType("js-bytecode", "text/javascript");
cc.preferAlternativeDataType("ammended-text", "text/plain");
cc.preferAlternativeDataType("something-else", "");
When loaded from the cache, the available alt-data type will be checked against
"js-bytecode" if the contentType is "text/javascript", "ammended-text" if the contentType is "text/plain" or "something-else" for all contentTypes.
Note that the alt-data type could be "something-else" even if the contentType is "text/javascript".
The preferences are saved as an nsTArray<mozilla::Tuple<nsCString, nsCString>>.

Right now, we have no idea how often an origin may offer us multiple alt-svc options. As we are considering racing multiple alt-svc connections (if they're available), it would be good to know how often we actually have (or would have, were we to store them) multiple options available. It would also be good to know how often an origin may change the target of its alt-svc mapping (even if there is only one target), as changes in target may make it useful to store/race multiple targets, as well.

Right now, as soon as we receive an alt-svc header or frame for an origin, we will overwrite any mapping we already have for that origin, even if it's still valid. This means that, should validation fail for the new mapping, we will have blown away a perfectly usable alt-svc mapping for no good reason. This patch prevents us from overwriting until we know the new mapping is good.
