Use a proper entropy source to generate file keys Summary: See T549. Under configurations where files are served from an alternate domain which does not have cookie credentials, we use random keys to prevent browsing, similar to how Facebook relies on pseudorandom information in image URIs (we could some day go farther than this and generate file sessions on the alternate domain or something, I guess). Currently, we generate these random keys in a roundabout manner. Instead, use a real entropy source and store the key on the object. This reduces the number of sha1() calls in the codebase as per T547. Test Plan: Ran upgrade scripts, verified database was populated correctly. Configured alternate file domain, uploaded file, verified secret generated and worked properly. Changed secret, was given 404.
