setup.py

add pretxncommit hook.

hook allows check of changeset after create, but before transaction
is committed.  hook failure rolls transaction back.

makes place for local policies like commit message must contain bug id
or reviewer signoff.

change also adds parent changeset ids to commit hook environment,
because is cheap and useful.
