Issue #22336 by quicksketch, scor, boombatower, and rfay. Move all core Drupal files under a core subdirectory.

- Patch #992564 by wojtha: t() or format_plural() inside watchdog() function call in tracker and action module.

- 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.

- Patch #122098 by Damien Tournoud, catch, mdixoncm: split comment.timestamp into 'created' and 'changed' columns, just like for nodes.

#564394 by Berdir and Crell: Removed database BC layer. nah nah nah nah... hey hey hey... gooood byeeee...

#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.

  et al.  Can you say 'registry'?  Drupal now maintains an internal registry of
  all functions or classes in the system, allowing it to lazy-load code files as
  needed (reducing the amount of code that must be parsed on each request). The
  list of included files is cached per menu callback for subsequent loading by
  the menu router. This way, a given page request will have all the code it needs
  but little else, minimizing time spent parsing unneeded code.

- Patch #245115 by kkaefer, John Morahan, JohnAlbin et al: after a long discussion we've decided to make the concatenation operator consistent with the other operators.

#200069 by keith.smith: new standard for 'more information' links in module help texts, as the handbook we referred to before was renamed

#197297 by DanW (as GHOP 17), and keith.smith: clean up lots of help texts, update to drag and drop functionality, drupal.module removal, etc

#186903 by marcingy, Rob Loach and chx: (regression) restore my recent posts functionality in tracker

#156392 by iacopopecchi, patch by myself: tracker module depends on comment module (uses its tables and constants without checking for the module being present), so this dependency should be codified in the .info file

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

- Patch #34755 by chx et al: faster menu system.  HEAD is temporary broken and there is no upgrade path yet.

#100516: CSS preprocessor to cache and compress all .css files. Benchmarks show up to 40% faster page loads.
