- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.

Roll-back of #595084; type-hinting parameters at stdClass makes it so you can't ever pass in another type of class.

#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.

#326539 by JohnAlbin, sun, cha0s, ultimateboy, Rob Loach, Damien Tournoud: Convert 'class' attribute to use an array, not a string.

- Patch #549432 by Bohjan, Gábor Hojtsy: create 'people and permissions' section in 'configuration and modules'.

- Patch #535564 by Gábor Hojtsy: the D7UX mockups call for a top level Content item, which would immediatey lead to the "Find content" screen. The current Drupal 7 code is almost there, but still has an RSS settings item blocking the implementation of this by default and aggregator and book also add subitems.

#373201 by moshe weitzman, chx, Frando, eaton: Allow renderable array properties to be passed directly to theme functions.

- Patch #319356 by recidive: clean up hook_nodeapi_ fucntion signatures and documentation because of previous node API clean-ups.

#313213 by maartenvg, Gábor Hojtsy: Add a 'title' attribute for permissions to allow for localization of permission names
