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
