Non-android scripts use these helpers, so this moves them outside of the //build/android directory. This also modifies the helpers in the following ways: * Renamed them. * Added more assert checks about valid paths * Fixed zip_directory() adding \s instead of /s on windows * Merged in zipalign logic * Changed compress_fn -> compress= (was unused) * Do not call atomic_output from zip_directory() * Updated all callers to do so explicitly.
