changegroup: use a copy of hookargs when invoking the changegroup hook

addchangegroup creates a runhook function that is used to invoke the
changegroup and incoming hooks, but at the time the function is called,
the contents of hookargs associated with the transaction may have been
modified externally. For instance, bundle2 code affects it with
obsolescence markers and bookmarks info.

It also creates problems when a single transaction is used with multiple
changegroups added (as per an upcoming change), whereby the contents
of hookargs are that of after adding a latter changegroup when invoking
the hook for the first changegroup.

Test safety for inconsistent rebase state, which may be created (and
forgotten) by Mercurial earlier than 2.7. This emulates Mercurial
earlier than 2.7 by renaming ".hg/rebasestate" temporarily.
