#915174 by sdboyer, sun: Remove pointless files[] declarations on files that are not declaring classes.

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

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

- Patch #634234 by jhodgdon, arianek, lisarex: better help for system module, syslog module, and simpletest module.

#606526 by axyjo and scor: Remove trailing whitespace and add newlines at end of files. Sorry, folks! But it is after code freeze. :)

#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 #572618 by effulgentsia, pwolanin, sun: all theme functions should take a single argument. Code clean-up and performance improvement. Woot.

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

  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.
