macros: code clean-up, use Python 2.4 style list comprehensions.

Follow-up to r9305, removed a left-over import of `ngettext`

Add new ![[KnownMimeTypes]] macro, for use in the TracGuide.

Closes #9097.

mimeview: some code clean-ups

mimeview: extend the KNOWN_MIME_TYPES list with all the `text/x-`''`type`''.

Part of #9097.

mimeview tests: make it possible to run the trac.mimeview.tests.api tests in isolation.

When run as part of the whole test suite, the `Converter[123]` components had the name `trac.mimeview.tests.api.converter[123]`, so they got enabled thanks to having the `trac.` prefix. When run directly, they had the name `__main__.converter[123]`, so they were not enabled, and `converters` extension point returned an empty list.

Fix an UnicodeDecodeError occurring in the timeline.rss template, due to passing a Genshi <Fragment> to a str format.

`gettext` doesn't have this problem, so use it here as it's anyway useful for typographical localization (no break space before ':').

InterWiki: make it possible to add parameters and fragment to InterWiki TracLinks.

Closes #8832.

formatter: the `Formatter.split_link` method is also useful without a Formatter, make a `split_url_into_path_query_fragment` utility method out of it.

bugzilla2trac: apply patch from Maarten Ter Huurne on #8229.
