update docs references, fix linkchecker and tests

added some code in linkchecker to check the generic::String docs when
trying to resolve links to alloc::string::String type alias. There's
some lazy-loading that the browser does, but linkchecker doesn't, so
maybe some general-purpose solution would be better, but this seemed
better than a big list of exceptions.
