- Put everything in the libuv transport package under `Microsoft.AspNetCore.Server.Kestrel.Transport.Libuv.*` namespaces.
- Move stuff in Transport.Libuv/Internal/Http and Transport.Libuv/Internal/Infrastructure to Transport.Libuv/Internal (keep the Networking directory for the libuv wrappers).
- Add `Libuv` prefix to most libuv internal classes.
- Rename `KestrelEngine` to `LibuvTransport`.
- Rename `SocketOutputConsumer` to `LibuvOutputConsumer`.
- Rename `SocketOutputProducer` to `OutputProducer`.
- Fix namespaces in `Microsoft.AspNetCore.Server.Kestrel.Core.`
This feature generates a unique ID per request. This unique ID can be
used in event source and logging.
Also, this change improves KestrelEventSource by moving it back into the
Kestrel.Core assembly and de-coupling from the Libuv transport. This
adds two new events, RequestStart and RequestStop, which can be used to
identify the correlation between connection ID and request trace
identifier.
