* Add heuristic checking for HTML anchors
Previously only anchors specified or generated in markdown could be
linked to, without complaint from the link checker. We now use a
simple heuristic check for `name` or `id` attributes.
Duplicate code has been refactored and all XML anchor checks updated
to use regex rather than substring match.
* Fix regexp and refactor
* cargo/manifests: allow user to use native-tls ...
... if `ring` can't be used on the user's platform (e.g. mips/ppc/riscv)
* CI: test for native tls build
Certain tests involving HTTP requests were sometimes hanging
indefinitely, so this uses Mockito for HTTP mocking. This seemingly
resolves the issue and makes these tests more reliable.
The existing can_fail_404_links test has been renamed to
can_fail_unresolved_links, to represent what actually occurs in the
test. The can_fail_404_links test now deals with a proper 404
response.
Just to be clear, the check_site test in the site component will
still create outgoing HTTP requests (due to the URLs used in the
test_site), so this commit only uses HTTP mocking where possible.
* Add anchor existant checking to link_checker component
* Oops, forgot some changes
* Drop scraper dependency and rework tests
* Handle name attributes
