Description of your pull request and other information

The AsianCrush extractor was partially broken (didn't extract description properly). This pull request fixes that, and also adds support for sister sites yuyutv and Midnight Pulp (closing #21281).

@remitamine sorry to bother you, but could you please take a look at this? (I think I've been understanding the code standards better now, so hopefully you won't have to leave as much feedback on this)

Merge video and playlist extractors into single video extractor and single playlist extractor.

[ealgase]

I can do that for the main AsianCrushIE, but for the Playlist IE, it currently requires an additional site specific variable (the _SITE_TITLE).

[dstftw]

Nothing stops from rewriting it to use re.sub.

[ealgase]

I don't understand? I'm referring to the last bit of this:

        title = remove_end(
            self._html_search_regex(
                r'(?s)<h1\b[^>]\bid=["\']movieTitle[^>]+>(.+?)</h1>', webpage,
                'title', default=None) or self._og_search_title(
                webpage, default=None) or self._html_search_meta(
                'twitter:title', webpage, 'title',
                default=None) or self._search_regex(
                r'<title>([^<]+)</title>', webpage, 'title', fatal=False),
            ' | %s' % self._SITE_TITLE)

I don't see how re.sub would allow that last bit to work without knowing the title of the site.

[dstftw]

re.sub(r'\s*\|\s*.+?$', '', title).

[ealgase]

OK, I've made the requested changes.

[dstftw]

Move flags into regex. Carry long lines.

[ealgase]

I'm confused about "Move flags into regex", I can't find a difference between the way this is implemented in other extractors.

[dstftw]

What difference are you even talking about?

[ealgase]

You said "Move flags into regex", I don't understand what you're asking me to do.

[dstftw]

Do you aware what flags are at all?

[dstftw]

Move .com part outside the inner group.

[dstftw]

Breaks on None title.
