Subject: Remove now-unused function pagespec_merge

Now that dependencies are a list of pagespecs with an implicit "or"
operation, there's no need to try to merge pagespecs under normal use.

ikiwiki-transition contains the only use of the function, so move
it there rather than deleting it entirely (it's used to concatenate all
admins' lists of locked pages).
