bundle2: automatically add 'targetphase' parameter in writenewbundle

If we are bundling secret changeset and the bundle will contain phase, we
request the changegroup to be applied as secret.

It will be useful for next patch as we are now sure that secrets changesets
are applied as secret and not applied as draft then forced to secret.

# dirstatenonnormalcheck.py - extension to check the consistency of the
# dirstate's non-normal map
#
# For most operations on dirstate, this extensions checks that the nonnormalset
# contains the right entries.
# It compares the nonnormal file to a nonnormalset built from the map of all
# the files in the dirstate to check that they contain the same files.
