This adds the new<scoped_allocator> header. Currently only
std::vector has the necessary support for C++0x allocators to be
usable with std::scoped_allocator_adaptor.
* include/Makefile.am: Add new header.
* include/Makefile.in: Regenerate.
* include/std/scoped_allocator: New.
* doc/xml/manual/status_cxx200x.xml: Update.
* testsuite/20_util/scoped_allocator/1.cc: New.
* testsuite/20_util/scoped_allocator/propagation.cc: New.
* testsuite/20_util/scoped_allocator/requirements/typedefs.cc: New.
* testsuite/20_util/scoped_allocator/requirements/
explicit_instantiation.cc: New.
Tested x86_64-linux, commited to trunk
Remaining allocator work is to make the other containers and
std::shared_ptr use the new C++0x model, and make std::function use an
allocator.
