revlog: don't cache parsed tuples in the C module

A cached entry creates ~8 Python objects per cached changeset, which
comes to around 200 Bytes per cached changeset on AMD64. Especially for
operations that touch a lot of changesets, that can easily sum up to
more than a 100MB of memory. Simple tests on large repositories show
<2% runtime penalty for ripping out the cache, even for cache heavy
operations like "hg log" for all revisions.
