Split warn.py into multiple files
* Split warning patterns into *_warn_patterns.py * Split project list into android_project_list.py * Split out the Severity class, to be changed later * Split core of warn.py into warn_common.py and leave only platform dependent code in warn.py. This allows the core logic be used with different parallel processing libraries. * Old warn.py just calls -m warn.warn. Test: path_to_build/tools/warn.py build.log Test: warn.py --url=http://cs/android --separator='?l=' build.log > warnings.html Change-Id: I6734e4472a21018cd5ce06d549f6dbca24f4de54
