Revert "Merge branch 'master' of https://github.com/wilsonsamm/libtranny"

This reverts commit 2b78922a12ef1be1d9c37a34adbe1548729c0ae8, reversing
changes made to 9e3ac23166415d0b8e2101030b7438fabff62162.

I've made some terrible mistakes which I've stashed and am now reverting. When
restructuring the "stack", some things ended up now not being executed in order
so I'll see to that later. I think some tidying up is in order.
