Shared: Provide custom isURI that rejects unknown schemes [isURI]
We also export the set of known `schemes`. The new function replaces the function of the same name from `Network.URI`, as the latter did not check whether a scheme is well-known. E.g. MediaWiki wikis frequently feature pages with names like `User:John`. These links were interpreted as URIs, thus turning internal links into global links. This is prevented by also checking whether the scheme of a URI is frequently used (i.e. is IANA registered or an otherwise well-known scheme). Fixes: #2713 Update set of well-known URIs from IANA list All official IANA schemes (as of 2017-05-22) are included in the set of known schemes. The four non-official schemes doi, isbn, javascript, and pmid are kept.
