Subject: [SERVER] iscsi refactor: First working version

Work towards simplifying the iscsi implementation has begun. Goals are:
- Simpler and easier to understand resource/lifecycle management of
  allocations
- Single-threaded architecture, making locking unnecessary
- Moving as many allocations as possible to the stack
- Making the call-stack more shallow for easier tracking of code flow
