This consists of three parts:
1. If the URL looks suspiciously like an archive, send a HEAD first to
check the Content-Type is HTML, to avoid downloading a large file.
Raise `_NotHTTP` if the content type cannot be determined, or
`_NotHTML` if it is not HTML.
2. Actually perform the request. Raise HTTP exceptions on network failures.
3. Check the Content-Type header to make sure we got HTML, and raise
`_NotHTML` otherwise.

The return value includes both URLs to project pages containing package
links, as well as individual package Link objects collected from other
sources.
This info is stored separately as:
(1) links from the configured file locations,
(2) links from the configured find_links, and
(3) urls to HTML project pages, as described by the PEP 503 simple
repository API.
