[rds-devel] [git pull] fixes to recv inc/frag cache

[Zach Brown]

Hey Andy,

Here's my first pass at those fixes to the recv inc/frag cache that we talked about.  The first patch is actually a silly unrelated fix, but it's obvious.

The rest of the patches make up our experiment to fix up work-in-progress patches in the series.  I tried to keep them super small so each is easy to audit on its own.  Each, once verified, should be merged with d34f7c7eae2d75344d8969757031e66dcdd9696d.  I arbitrarily chose "REBASE" as a subject prefix to tell us that we want to fold those patches back into the devel branch before pushing the result to the outside world :).

These survived rds-stress bcopy over here.  Let me know if there's anything I need to fix up.

The following changes since commit 6cc40ca4e7d4708298c5a695c06f156c2698254b:
