If `StateFilter` specifies a state set which we will have regardless of
state-syncing, then we may as well return it immediately.

Refactor `resolve_state_groups_for_events` to not pull out full state when no state resolution happens. (#12775)

Give a meaningful error message when a client tries to create a room with an invalid alias localpart. (#12779)

The main differences are:
- values with delimiters (such as colons) should be quoted, so always
  quote the origin, since it could contain a colon followed by a port
  number
- should allow more than one space after "X-Matrix"
- quoted values with backslash-escaped characters should be unescaped
- names should be case insensitive
