rust-index: stop instantiating a C Index

The only missing piece was the `cache` to be returned from
`revlog.parse_index_v1_mixed`, and it really seems that it is
essentially repetition of the input, if `inline` is `True`.
Not worth a Rust implementation (C implementation is probably there
for historical reasons).

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