Description

Now that Yetus has had a release, we should rip out the components that make it up from dev-support and replace them with wrappers. The wrappers should:

• default to a sane version
• allow for version overrides via an env var
• download into patchprocess
• execute with the given parameters

Marking this as an incompatible change, since we should also remove the filename extensions and move these into a bin directory for better maintenance towards the future.
