Bare QUIC demo working
commit d3939b3d6568cf4262c0391486a5203873b68bfc
Author: Neil Alexander <neilalexander@users.noreply.github.com>

Support bare Yggdrasil sessions with encrypted QUIC
* Initial QUIC work
* Update Yggdrasil demo
* Make sure that the federation sender knows how many pending events are in the database when the worker starts
* QUIC tunables
* pprof
* Don't spin
* Set build info for Yggdrasil
* Initial work on persistent queues
* Update index for event ID and server name
* Put things into database (postgres for now)
* Duplicate postgres code into sqlite for now just to stop build errors, will fix SQLite soon
* Fix table name
* Fix index
* Fix table name
* Use RETURNING because LastInsertID is not supported by postgres
* Use functions
* Marshal headered event

* Don't block if there are PDUs waiting

* well this is tedious
* Fix race in incomplete transactions

* Use a fork of pq which supports userCurrent on wasm
* Use sqlite3_js driver when running in JS
* Add cmd/dendritejs to pull in sqlite3_js driver for wasm only
* Update to latest go-sqlite-js version
* Replace prometheus with a stub. sigh
* Hard-code a config and don't use opentracing
* Latest go-sqlite3-js version
* Generate a key for now
* Listen for fetch traffic rather than HTTP
* Latest hacks for js
* libp2p support
* More libp2p
* Fork gjson to allow us to enforce auth checks as before
Previously, all events would come down redacted because the hash
checks would fail. They would fail because sjson.DeleteBytes didn't
remove keys not used for hashing. This didn't work because of a build
tag which included a file which no-oped the index returned.
See https://github.com/tidwall/gjson/issues/157
When it's resolved, let's go back to mainline.
* Use gjson@1.6.0 as it fixes https://github.com/tidwall/gjson/issues/157
* Use latest gomatrixserverlib for sig checks
* Fix a bug which could cause exclude_from_sync to not be set
Caused when sending events over federation.
* Use query variadic to make lookups actually work!
* Latest gomatrixserverlib
* Add notes on getting p2p up and running
Partly so I don't forget myself!
* refactor: Move p2p specific stuff to cmd/dendritejs
This is important or else the normal build of dendrite will fail
because the p2p libraries depend on syscall/js which doesn't work
on normal builds.
Also, clean up main.go to read a bit better.
* Update ho-http-js-libp2p to return errors from RoundTrip
* Add an LRU cache around the key DB
We actually need this for P2P because otherwise we can *segfault*
with things like: "runtime: unexpected return pc for runtime.handleEvent"
where the event is a `syscall/js` event, caused by spamming sql.js
caused by "Checking event signatures for 14 events of room state" which
hammers the key DB repeatedly in quick succession.
Using a cache fixes this, though the underlying cause is probably a bug
in the version of Go I'm on (1.13.7)
* breaking: Add Tracing.Enabled to toggle whether we do opentracing
Defaults to false, which is why this is a breaking change. We need
this flag because WASM builds cannot do opentracing.
* Start adding conditional builds for wasm to handle lib/pq
The general idea here is to have the wasm build have a `NewXXXDatabase`
that doesn't import any postgres package and hence we never import
`lib/pq`, which doesn't work under WASM (undefined `userCurrent`).
* Remove lib/pq for wasm for syncapi
* Add conditional building to remaining storage APIs
* Update build script to set env vars correctly for dendritejs
* sqlite bug fixes
* Docs
* Add a no-op main for dendritejs when not building under wasm
* Use the real prometheus, even for WASM
Instead, the dendrite-sw.js must mock out `process.pid` and
`fs.stat` - which must invoke the callback with an error (e.g `EINVAL`)
in order for it to work:
```
global.process = {
pid: 1,
};
global.fs.stat = function(path, cb) {
cb({
code: "EINVAL",
});
}
```
* Linting
