This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
This also removes the code for displaying `gemini://` documents. We
currently don't load documents from that protocol anyway - we hit
`attempt_to_create_a_non_fetch_scheme_document()` in `Navigable.cpp`
which is just a stub. It looks like we should be handling those
separately from regular "fetch" documents, so that's a task for a
future person.
(Apologies for bad commit title, it's hard to explain in such a short
space!)
We're going to need to call this for producing markdown and gemini
documents, both of which need a Document and Realm to fetch the entire
response body, so that they can then generate their HTML. So this
commit modifies `create_document_for_inline_content()` to take a lambda
instead of a fixed HTML string, to support these uses.
Also, we always return a nonnull pointer, so make that the return type.
This is a move and change in the same commit, (Sorry!) but all the
changes are to the function signature and step 6.
There's no mention in the spec of this being optional, all the places
that call it always pass a NavigationParams directly, and we're
VERIFYing that it's got a value too!
Implements:
https://html.spec.whatwg.org/multipage/browsing-the-web.html#attempt-to-populate-the-history-entry's-document
This is going to be a replacement for `FrameLoader::load()` after
switching to navigables.
Brief description of `populate_session_history_entry_document`:
- If navigation params have url with fetch scheme then DOM document
will be populated by fetching url and parsing response. This
is going to be a replacement for `FrameLoader::load(AK::URL&)`.
- If url in navigation params is abort:srcdoc then DOM document
will be populated by parsing HTML text passed in document resource.
This is going to be a replacement for `FrameLoader::load_html()`
