discovery: add extinct changesets to outgoing.excluded
Before this change, push would incorrectly fast-path the bundle
generation when extinct changesets are involved, because they are not
added to outgoing.excluded. The reason to do so are related to
outgoing.excluded being assumed to contain only secret changesets by
scmutil.nochangesfound(), when displaying warnings like:
changes found (ignored 9 secret changesets)
Still, outgoing.excluded seems like a good API to report the extinct
changesets instead of dedicated code and nothing in the docstring
indicates it to be bound to secret changesets. This patch adds extinct
changesets to outgoing.excluded and fixes scmutil.nochangesfound() to
filter the excluded node list.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
# [hooks]
# changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
# - <hookname> is a mandatory argument (e.g. "changegroup")
# - [exit] is the exit code of the hook (default: 0)
# - [output] is the name of the output file (default: use sys.stdout)
# the file will be opened in append mode.
