scripts/contrib: Add override conversion script
This adds a script I've developed to migrate metadata to use the new override syntax. It is a bit rough but since its for a single use with validation, it doesn't need to be perfect. It is run simply as: scripts/contrib/convert-overrides.py <directory> It is setup and has been tested to work with OE-Core, Bitbake, yocto-docs, meta-yocto, meta-gplv2 and meta-mingw. For OE-Core, it converts around 10,100 lines with about 34 manual fixes needed. For other layers it would need updating for override names and exclusions for functions/variable names with "append", "prepend" or "remove" in them. (From OE-Core rev: e8fc67f6f6baf54ccdf548b947c35dea926842c3) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
