05ad06fbc1 Only enclose get_page in iorepeat in ILIAS crawler
We previously also gathered in there, which could lead to some more
surprises when the method was retried.

b44b49476d Fix noncritical and anoncritical decorators
I must've forgot to update the anoncritical decorator when I last changed the
noncritical decorator. Also, every exception should make the crawler not
error_free, not just CrawlErrors.

3d4b997d4a Retry crawl_url and work around Python's closure handling
Closures capture the scope and not the variables. Therefore, any
type-narrowing performed by mypy on captured variables is lost inside
the closure.

afac22c562 Handle abort in exclusive output state correctly
If the event loop is stopped while something holds the exclusive output, the
"log" singleton is now reset so the main thread can print a few more messages
before exiting.

552cd82802 Run async input and password getters in daemon thread
Previously, it ran in the event loop's default executor, which would block until
all its workers were done working.

If Ctrl+C was pressed while input or a password were being read, the
asyncio.run() call in the main thread would be interrupted however, not the
input thread. This meant that multiple key presses (either enter or a second
Ctrl+C) were necessary to stop a running PFERD in some circumstances.

This change instead runs the input functions in daemon threads so they exit as
soon as the main thread exits.

4b104b6252 Try out some HTTP authentication handling
This is by no means final yet and will change a bit once the dl and cl
are changed, but it might serve as a first try. It is also wholly

e4f9560655 Only retry on aiohttp errors in ILIAS crawler
This patch removes quite a few retries and now only retries the ilias
element method. Every other HTTP-interacting method (except for the root
requests) is called from there and should be covered.

In the future we also want to retry the root a few times, but that
will be done after the download sink API is adjusted.
