Mostly generated using

make check COMPILER_EXTERNAL_TOOL=1 CCACHE_PREFIX=clang-rename-wrapper RENAME_ARGS="-qualified-name=Rectangle -new-name=tools::Rectangle"

Except some modules have their own foo::tools namespace, so there have
to use ::tools::Rectangle. This commit just moves the class from the
global namespace, it does not update pre/postwin.h yet.
