[PATCH v5 00/37] libctf linking, final cycle

[Nick Alcock <nick dot alcock at oracle dot com>]

The posted portion of this series only contains those patches which have seen
changes more significant than tabdamage fixes since v4, to avoid pointlessly
bombing the list with stuff you've all seen already.  Since some of those are
outside my purview, I'll hold off pushing until you've said you're happy with
them.  (It seems likely: the changes are uncontroversial.  Some are literally
just tabdamage fixes for stuff that went in in previous series.)

I have also got --disable-libctf working, but that's for another patch series
I think: this one is quite long enough!
