Fixes #1158
Add config options WAGTAILDOCS_CONTENT_TYPES and WAGTAILDOCS_INLINE_CONTENT_TYPES to determine the Content-Type and Content-Disposition headers returned for documents when using the Django serve view, and default to application/pdf being served inline.
Add user_display_name template filter to simplify user display code
This replaces the `{{ some_rambling_expression_evaluating_to_a_user.get_full_name|default:some_rambling_expression_evaluating_to_a_user.get_username }}` pattern used all over the place.
Display user's full name (where available) in LogEntry listings
Don't use full name if it consists of whitespace (which happens on our test user models)
release note
- Add anyascii to replace unidecode
- Update wagtail.core.utils.string_to_ascii to use anyascii.
- Anyascii has a similar but not exactly the same encoding - see updates to tests.

Fixes #6288
Many of the oembed endpoints currently listed with an http:// URL now redirect to https://. Changing these to https:// saves a redundant redirect and avoids failures where the http URL has been blocked (see #6288). Also simplified the patterns for matching http or https - the group in `http(?:s)?` is redundant and should just be `https?`.
