- Move some code into module part to avoid dependency from IStorage in SystemLog
- Remove extra headers from SystemLog.h
- Rewrite some code that was relying on headers that was included by SystemLog.h
v2: rebase
v3: squash move into module part with explicit template instantiation
(to make each commit self compilable after rebase)
