#678714 by effulgentsia: Unify use of theme hook / template suggestions, fix clobbering problems, and improve suggestion discovery performance.

- Patch #652834 by yched, effulgentsia: changed Field formatters as render arrays to increase performance (and to clean-up the code).

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

#600974 by effulgentsia, JohnAlbin, sun, and Damien Tournoud: Allow theme functions to take one argument without any hacks. NOTE: This is an API change in hook_theme().

- Patch #603236 by bjaspan, catch: add count facility to field_attach_query(). Was ready before code freeze.

- Patch #470242 by yched, bjaspan: fixed namespacing for bundle names to avoid users rendering their site unusable.

#560780 by quicksketch, ksenzee, Arancaytar, yched, and arianek: Added Image Field to image.module. Hellooooo, native image handling in core! :D

- Patch #597832 by markus_petruxm: add (),  arguments to field_access() to enhance the context for hook_field_access().

- Patch #443422 by yched, bjaspan | chx, merlinofchaos, Scott Reynolds, plach, profix898, mattyoung: added support for pluggable 'per field' storage engine. Comes with documentation and tests.

The Field Attach API uses the Field Storage API to perform all "database access". Each Field Storage API hook function defines a primitive database operation such as read, write, or delete. The default field storage module, field_sql_storage.module, uses the local SQL database to implement these operations, but alternative field storage backends can choose to represent the data in SQL differently or use a completely different storage mechanism such as a cloud-based database.

- Patch #569362 by scor, effulgentsia, catch: add attributes and title_attributes() variables for tpl files so that RDFa and Microformats can be implemented.

#569072 by rcross and yched:  Clean field_attach_()* namespace by renaming and moving non-crud functions.

#367567 by effulgentsia, yched, quicksketch, sun, and chx: Move AHAH-'add more' to the new generic AHAH callback, and add support for form definition functions being kept in non-.module files.

#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.
