[ros-diffs] [ion] 19847: - Fix KeAttackProcess, KeStackAttachProcess, KeUnstackDetachProcess and KeDetachProcess. The code was brain-dead and I must've been drunk when I first wrote it.

- Fix KeAttackProcess, KeStackAttachProcess, KeUnstackDetachProcess and
KeDetachProcess. The code was brain-dead and I must've been drunk when I
first wrote it.
- Update some NDK definitions and some fixes.
- Update HAL Private Dispatch Table to 2.0
- Make RtlIpv* API definitions more correct.
