#500866 by boombatower, solotandem: Remove t() from assertion messages in SimpleTest, so translators do not get 1000s of bogus strings.

#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.

- Patch #513592 by Damien Tournoud: make it faster to rebuild the registry, mainly to improve performance of SimpleTest.

- Patch #464714 by chx, DamZ: speed up the tests by bringing unit tests backt to live.  Unit tests bootstrap faster and have the potential to speed up testing. We'll need help converting tests where possible.

#376129 by boombatower, Damien Tournoud, and chx: Change getInfo() to a static method to reduce memory footprint of SimpleTest.

- Patch #298600 by chx, justinrandell, Damien, et al: make module_implements work regardless of bootstrap phase.
