Land #3252, check() functionality for Heartbleed
First, undo #3252. Sorry about that.

undo #3252 completely. This means a reimplementation of @dchan's work,
but his intent was simply to implement a check_host() that doesn't
actually pull memory, so that should be pretty straight forward with the
new structure of the module.
Clean up whitespace. Protip: use commit hooks
Reimplement a check.
Looks like an autocorrect ran wild on TLS_CALLBACK

Whoops.
