Implement "An API for deciding whether plugins should cause recompilation"
This patch implements the API proposed as pull request #108 for plugin
authors to influence the recompilation checker.
It adds a new field to a plugin which computes a `FingerPrint`. This is
recorded in interface files and if it changes then we recompile the
module. There are also helper functions such as `purePlugin` and
`impurePlugin` for constructing plugins which have simple recompilation
semantics but in general, an author can compute a hash as they wish.
Fixes #12567 and #7414
