templater: add shorthand for building a dict like {"key": key}

Like field init shorthand of Rust. This is convenient for building a JSON
object from selected keywords.

This means dict() won't support Python-like dict(iterable) syntax because
it's ambiguous. Perhaps it could be implemented as 'mapdict(xs % (k, v))'.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
