This simplifies the logic by separating thread local notifications from cross-thread notifications, as well as replacing lockless operations by a spin lock. The thread local variant of ManualEvent is now also separated into a LocalManualEvent type.
- Moves a lot of stuff from vibe.core.core to vibe.core.task
- Introduces TaskScheduler to unify the scheduling process
- Refines how tasks are scheduled and processed (can push to the front of the task queue and uses a marker task to keep track of the spot up to which to process)
- Start to add proper support for task interrupts and timeouts by properly cancelling in-flight async operations
- Work on ManualEvent - still not functional for the shared case
- Implement proper IP address parsing in NetworkAddress
The library is able to support simple TCP servers in the current state. The API is still mostly compatible with mainline vibe.d, but the driver systen has been replaced by the eventcore library and sockets/files/timers/... are now structs with automatic reference counting instead of GC collected classes. The stream interfaces have been removed for now.
