Patch Roundup: merge-tracking

In an effort to make sure that no patch gets forgotten, I'm gradually
making some progress on the patches from this summer. There are a few
merge-tracking patches which I still have in limbo. I therefore solicit
feedback regarding the status of the following patches. (Obsolete,
applied, rejected, etc.)

If I don't hear anything back, I will assume that these patches are
still valid, and file them in the issue tracker.

So, to help avoid needless cluttering of the issue tracker, please
provide some feedback on the above patches.

Thanks,
