narrow: detect if narrowspec was changed in a different share

With this commit, `hg share` should be usable with narrow
repos. Design explained on
https://www.mercurial-scm.org/wiki/NarrowSharePlan

I was running into cache invalidation problems when updating the
narrowspec. After spending a day trying to figure out a good solution,
I resorted to just assigning repo.narrowpats and repo._narrowmatch
after invalidating them.
