Title: Review: remove old boost <1.40 vestiges

For quite some time now, we've said that our Boost minimum requirement was at least 1.40.

This patch removes a bunch of crufty #if's that handle older Boost versions (1.35 and 1.36 in many cases).

Now we have very few places that need to distinguish between different Boost versions, since all of our boost use is of parts of their API that have not changed for years.

This deprecates hash.h, which I am leaving in place for the time being (to not screw up any packages that depend on including it, for now).
