Helps allocators which can't use incomplete pointers, and avoid using
base pointers where that might not be possible. And some other
reorganization. Storing arguments to emplace in a structure when
variadic template parameters aren't available. Changed some of the odd
design for working with older compilers.

Something is causing the sun compiler to crash. I don't know if it's the
member detection or testing if the member if callable, so try disabling
the callable test to see if that works better.

On vacpp `has_select_on_container_copy_construction` was incorrectly returning
positive for a non-const `select_on_container_copy_construction`. This resulted
in a compile error as it tried to call it for a const allocator. The workaround
seemed to have just made things worse so I'm reverting it. It's actually not
that bad a problem as a non-const `select_on_container_copy_construction` is
probably a mistake.

- Remove use of BOOST_DEDUCED_TYPENAME and BOOST_UNORDERED_PAIR_CAST, it's
unlikely that the compilers which require them will be able to cope with the
new version of unordered.
- Use the old equality algorithm if BOOST_UNORDERED_DEPRECATED_EQUALITY is
defined.
- Use SFINAE to control which overloads of `construct_impl` are available.
Fixes problems with differing overload resolution on different compilers.
- Support for piecewise pair construction.
- Only support the old variadic pair construction when
BOOST_UNORDERED_DEPRECATED_PAIR_CONSTRUCT is defined (also fixed some bugs).
- Avoid instantiating BOOST_RV_REF for non-classes.
- Support optional allocator member functions for compilers with SFINAE
expressions and Visual C++ 9.0/10.0
- Follow boost macro naming conventions.
- Improved portability for `allocator_traits` emulation.
Current compiler support:
- Full support for GCC 4.4+, Visual C++ 9.0+, Clang.
- All other compilers odn't support optional allocator members.
- No other errors for GCC 3.4.6+, Visual C++ 8.0, Intel, Pathscale.
- Visual Age has a compile error if `select_on_container_copy_construction`
isn't `const` (it should ignore it).
- `select_on_container_copy_construction` detection doesn't work on Sun.
- `unnecessary_copy_tests` is failling for vacpp on AIX, but not on linux.
- Warnings causing failures for Visual C++ with STLport and WM5.

Another stab in the dark. Doing SFINAE in the return type appears to
work well, apart for Visual C++ 8.0. Will have to see how the test
results go for some compilers.
