The obsolete._enabled flag has become a config option. This updates all but one
of the tests to use the minimal number of flags necessary for them to pass. For
most tests this is just 'createmarkers', for a couple tests it's
'allowunstable', and for even fewer it's 'exchange'.
When you have obsolescence marker that apply to a pulled changesets, the added
changeset is immediately filtered. Then the list of added changeset needs to be
build against and unfiltered repo.
Obsolete markers wide-usage and propagation should be avoided by default until
the obsolete feature is more mature.
This changeset introduce the `_enable` variable and prevent the creation of
obsolete marker if the feature is set to `False` (the default).
More limitation comes in followup changesets.
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.
