Seems to be better in some cases. For example, better forwarding if
rvalue references are supported but variadic template parameters aren't.
Also can use `boost::move` when inserting.
Older versions of gcc still fail this test. They perform more moves than
expected. It might be a limitation of Boost.Move, or maybe just poor
copy optimization.

Store nodes in a single linked list, with hash values so that their
buckets can be found when needed. Iterators now only have to store a
pointer to the node and don't have to iterate over empty buckets to
reach the next node. This allows the container to meet the iterator
requirements - fixing the speed issues with `equal_range` and `erase`.
Also, define iterators in their own namespace, so that they don't
accidentally pull in detail functions via ADL.
I've simplified the code slightly by removing some of the special
cases for empty containers. Renamed a few things as well and other
minor changes that were made as I went along.

In the draft standard the std::pair constructor from another pair is
only considered when overloading if both members are implicitly
constructible to their corresponding members. This breaks one of the
unordered tests which required an explicit conversion, so change it to
only require an implicit conversion.

- Avoid using operator& with the value type.
- More comments in headers.
- Remove old clang workaround.
- Adjust use of inline to make Borland a little happier.
- Avoid `-Wconversion` warnings.

I accidentaly removed the good code and left the workaround in. Also, a
correction to the comment: I think bug was only in a unreleased version
of clang.

Borland is having some issues with the existing tests, since they call
inline functions before they're defined. It might be right to, although
all the other compilers are fine with it. But the test isn't really what
the forward headers are intended for. Try to make the tests better
represent the intent, and possibly work on Borland.
