stapled - A OCSP stapling daemon

Note: This is still a work in progress, idk if I'd actually use it yet!

A caching OCSP daemon that makes stapling less painful. Inspired in large part by the notes written on the topic by Ryan Sleevi.

Intended to be easily proxyabe and distributable (and make life at least somewhat easier for applications implementing OCSP stapling in a less than ideal way).
