Switch a number of files to C++.

http://i1.kym-cdn.com/photos/images/original/000/242/631/382.gif

In the first step, switch C files to C++ individually, keeping
everything in internal.h C-compatible. We'll make minimal changes needed
to get things compiling (notably a lot of goto errs will need to turn to
bssl::UniquePtr right away), but more aggressive changes will happen in
later steps.

(To avoid a rebase, I'm intentionally avoiding files that would conflict
with CLs in flight right now.)
