This adds more tests to `curl_spec.rb` to increase test coverage.
This brings almost all of the methods that don't make network
requests up to 100% line and branch coverage (the exception being
some guards in `parse_curl_output` that shouldn't happen under
normal circumstances).
In the process of writing more tests for `parse_curl_response`, I
made some tweaks to remove checks for conditions that shouldn't ever
be true (e.g., `match["code"]` isn't optional, so it will be present
if `HTTP_STATUS_LINE_REGEX` matches) and to refactor some others. I
contributed this method a while back (9171eb2), so this is me coming
back to clarify some behavior.
- Some casks have URL arguments like "referer" (spelled wrong, that's
intentional in the HTTP spec).
- The audit for one such cask, `iThoughtsX`, was failing because the
"referer" wasn't getting passed through to cURL so the access would
404.

Update base URL when there is an absolute location, so that following
relative locations are considered relative to the new base.
Consider below cURL output for https://example_one.com:
HTTP/1.1 302 Moved Temporarily
Location: https://example_two.com
HTTP/1.1 302 Moved Temporarily
Location: /foo/
HTTP/1.1 200 OK
The final URL should be https://example_two.com/foo/ rather than
https://example_one.com/foo/.
The return hash from `#curl_http_content_headers_and_checksum`
contains a `:status`, which is the status code of the last response.
This string value comes from `#parse_curl_response`, where the key is
`:status_code` instead.
Aligning these keys technically allows us to pass either of these
hashes to the `#url_protected_by_*` methods, as both contain
`:status_code` and `:headers` in the expected format.
Before `#parse_curl_output` was introduced and related methods were
updated to use it, `#url_protected_by_cloudflare?` and
`#url_protected_by_incapsula?` were checking a string of all the
headers from a response and using a regex to check related header
values.
However, when `#curl_http_content_headers_and_checksum` was updated
to use `#parse_curl_output` internally, the `:headers` value became
a hash generated by `#parse_curl_response`. The `#url_protected_by_*`
methods were updated to work with the hash value but this wasn't able
to fully replicate the previous behavior because
`#parse_curl_response` was only keeping the last instance of a given
header (maintaining pre-existing behavior). This is an issue for
these methods because they check `Set-Cookie` headers and there can
be multiple instances of this header in a response.
This commit updates these methods to handle an array of strings in
addition to the existing string support. This change ensures that
these methods properly check all `Set-Cookie` headers, effectively
reinstating the previous behavior.
Past that, this updates one of the early return values in
`#url_protected_by_cloudflare?` to be `false` instead of an implicit
`nil`. After adding a type signature to this method, it became clear
that it wasn't always returning a boolean value and this fixes it.
`Curl#parse_curl_response` only includes the last instance of a given
header in its `:headers` hash (replicating pre-existing behavior).
This is a problem for headers like `Set-Cookie`, which can appear more
than once in a response.
This commit addresses the issue by collecting duplicate headers into
an array instead. Headers that only appear once in the response will
still have a string value but headers that appear more than once will
be an array of strings. Whenever headers from `#parse_curl_response`
are used (directly or indirectly), it's important to conditionally
handle the expected types.
