* When --copy-out is used:
* copy build.rs output files to ./out
* add a genrule module to copy ./out/* files to its output dir
* add this copy-out genrule module into the srcs list
This makes include! with $OUT_DIR path work without local patch.
This only works for the root directory (package).
* Upgrade to python3 for some required shutil and glob functions.
* Unified dump_srcs_list for defaults and non-defaults modules.
* dump_android_property_list output only one line for a single item list.
