Sync refactor — Part 1 (#1688)
* It's half-alive * Wakeups largely working * Other tweaks, typing works * Fix bugs, add receipt stream * Delete notifier, other tweaks * Dedupe a bit, add a template for the invite stream * Clean up, add templates for other streams * Don't leak channels * Bring forward some more PDU logic, clean up other places * Add some more wakeups * Use addRoomDeltaToResponse * Log tweaks, typing fixed? * Fix timed out syncs * Don't reset next batch position on timeout * Add account data stream/position * End of day * Fix complete sync for receipt, typing * Streams package * Clean up a bit * Complete sync send-to-device * Don't drop errors * More lightweight notifications * Fix typing positions * Don't advance position on remove again unless needed * Device list updates * Advance account data position * Use limit for incremental sync * Limit fixes, amongst other things * Remove some fmt.Println * Tweaks * Re-add notifier * Fix invite position * Fixes * Notify account data without advancing PDU position in notifier * Apply account data position * Get initial position for account data * Fix position update * Fix complete sync positions * Review comments @Kegsay * Room consumer parameters
