Merge branch 'master' of scm.dev.nokia.troll.no:qt/berlin-staging-1 into master-integration

* 'master' of scm.dev.nokia.troll.no:qt/berlin-staging-1: (22 commits)
  fix "configure -fast" on Windows for other maketools than nmake
  Get qmake to add pdb files to install target in debug configuration.
  add TARGET_PLATFORM to qmakespecs with MAKEFILE_GENERATOR = UNIX
  give symbian an own platform mode
  deprecate -win32/-unix/-macx which set both host and target mode
  decouple host platform mode from target platform mode
  factor out applyHostMode()
  make QMAKE_QMAKE and QMAKE_EXT_OBJ magic builtins
  use QDir::separator() instead of Option::dir_sep where appropriate
  simplify string ops
  sanitize evaluation of OS scopes
  instead of hard-coding recursion for symbian, add it to the specs
  add possibility to request project recursion from within a pro file
  fix ts-assistant target
  use QList::reserve() as appropriate
  optimize appending of (empty) lists to (empty) lists
  suppress pointer aliasing warnings
  Fix compilation with namespace.
  Assistant: Make ~AbstractHelpViewer() virtual.
  Prepare German translations for 4.7 (except Quick).
