#516138 follow-up by yched: Instead of a full menu rebuild, set a variable indicating it's needed. Speeds up tests by a factor of at least two.

#162788 by dww, Dave Reid, and JohnAlbin: Add option to include modules that aren't enabled in Update Status.

#497118 by chx, catch, pwolanin, JoshuaRogers, and Jacob Singh: Remove the function registry. While the hope was that this would result in improved performance for low-end hosts, it comes at the expense of critical development experience problems and less benefit than something like APC. Class registry remains intact to facilitate autoloading.

Of all the patches to accidentally commit without a message. :( Rolling back registry rip. Let's try that again.
