For the latest snapshot, I dropped the musttail workarounds except for ones already about to be merged. Story is in bug 951999 but more to do here. The upstream bugs are still being worked on (with some patches committed already).

This brings us up to date with trunk, with various musttail fixes. Given we're pretty close to branching, this seems like a better idea than cherry-picking various bits and then finding we're missing something later. All known musttail issues should be fixed now.
