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

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

- Patch #373613 by drewish, quicksketch: working around some Debian issues.  They ship a different GD library.

  times (such as crop, scale, then desaturate) without quality loss, we need to
  pass images by their raw GD (or other library) resources rather than re-opening
  the same image repeatedly, which causes wasted processing and loss of quality when
  using JPEG images.  This patch reworks the image toolkits, adds some new image
  manipulations and adds some impressive SimpleTests.
