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.
