Simon Tatham e7d51505c7 Utility function strbuf_dup. ...

If you already have a string (of potentially-binary data) in the form
of a ptrlen reference to somewhere else, and you want to keep a copy
somewhere, it's useful to copy it into a strbuf. But it takes a couple
of lines of faff to do that, and it's nicer to wrap that up into a
tiny helper function.

This commit adds that helper function strbuf_dup, and its non-movable
sibling strbuf_dup_nm for secret data. Also, gone through the existing
code and found a bunch of cases where this makes things less verbose.
