Replace cutils/log.h and rationalize log/log.h and android/log.h

- cutils/log.h treat as deprecated and lead by example
- android/log.h to be used instead of log/log.h if required
- add system includes that are assumed as side effects of log.h
- modules that use SLOG should use SLOG for all logging (installd)
- define LOG_TAG first
- remove logging infrastructure if not used
