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.

Will need to deprecate the old variadic style pair construction, also
should look into extract_key, was written for compatibility with older
compilers that are no longer supported.

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.

It seems that the problem is calling sizeof on a dependent type when the
containers have only been used by reference. So by putting in these
dummy structures with the containers as members, it helps the compiler
instantiate the class to the level where sizeof works. I hope.

- More template use, less preprocessor use.
- Removed some of the Visual C++ 6 workarounds.
- Reduced memory use of the main object.
- Split into smaller headers.
