Re: [PoC] Improve dead tuple storage for lazy vacuum

Of course, "clean" is a relative term. While making a small bit of progress working in tidbitmap.c earlier this week, I thought it useful to prototype some things in the tidstore, at which point I was reminded it no longer compiles because of my recent work. I put in the necessary incantations so that the v32 tidstore compiles and passes tests, so here's a patchset for that (but no vacuum changes). I thought it was a good time to also condense it down to look more similar to previous patches, as a basis for future work.
