As discussed on the mailing list, here is my initial pass at the variadic formatting library.

Formatters are provided for integral, character, string, and pointer types.  More complex formatters such as those required for `chrono` classes are not yet provided, but they are lower priority.

Note that this patch is blocked on https://reviews.llvm.org/D25497, so while I welcome reviews to this any time, it can't go in until that one is approved.

Adding a bunch of people that expressed interest in this from the list.
