- Added property `KestrelServerOptions.MaxRequestBufferSize`
- Default is 1,048,576 bytes (1MB)
- If value is null, the size of the request buffer is unlimited.
- Fixed bug in `IConnectionControl.Resume()` where `_socket.ReadStart()` can throw if the socket is already disconnected.
- Made `UvStreamHandle.ReadStop()` idempotent, to match `uv_read_stop()`.
