[IMP] See below.

- Revoke OTA flag for now inside bootloader (newosldr #4)
- Rework Comm as SCI (System Call Interface) (newoskrnl #3)
- Rework and fix some parts of the scheduler (newoskrnl #2)
- Return from thread when region is zero (newosldr #1)
- Separate allocation functions and c++ runtime from each other. (DDK #5)
- Rename kHartStandard to kStandard (newoskrnl #6)
