The font lock of assignments with type hints in Python is rather bad.
Consider the following example:

    from typing import Mapping, Tuple, Sequence
    var1: int = 5
    var2: Mapping[int, int] = {10: 1024}
    var3: Mapping[Tuple[int, int], int] = {(2, 5): 32}
    var4: Sequence[Sequence[int]] = [[1], [1, 2], [1, 2, 3]]
    var5: Sequence[Mapping[str, Sequence[str]]] = [
        {
            'red': ['scarlet', 'vermilion', 'ruby'],
            'green': ['emerald green', 'aqua']
        },
        {
            'sword': ['cutlass', 'rapier']
        }

As things stand right now, only ‘var1’ would be highlighted.  To make
things worse, the ‘Mapping’ type hint of ‘var2’ would also be
highlighted, which is entirely incorrect.

This commit makes all of ‘var1’ through ‘var5’ be highlighted
correctly.

Various fixes and backward compatibility for gnus-search

* lisp/gnus/gnus-group.el (gnus-group-make-search-group,
gnus-group-read-ephemeral-search-group): Check for and accept the old
nnir-* spec keys.
* lisp/gnus/gnus-search.el (shared-initialize): Use
generate-new-buffer instead of doing it ourselves.
(gnus-search-server-to-engine): Raise an informative error explicitly
if we can't find a search engine, rather than letting it fall through
to something less helpful.
(gnus-search-make-spec): Add `gnus-search--complete-key-data' to
`completion-at-point-functions' locally, not globally.
