views: branch/paginate: teach "next" link to respect 'max_pages'

Pagination link "next" does not respect 'max_pages', thus it incorrectly
remains enabled on the final page capped by 'max_pages'. When clicked,
the user is taken to a "404 Page not found" error page, which makes for
a poor user experience.

Fix this problem by teaching the "next" link to respect 'max_pages'.

(As a side-effect, this also causes 'serve' mode to respect 'max_pages',
which was not previously the case. This change of behavior is
appropriate since it brings 'serve' mode, which is intended primarily
for testing, more in line with 'generate' mode.)
