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.
[SVN r71327]
- 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.

Use normal references for the move members, reset the source buckets_ pointer to stop the buckets getting deleted, and remove a superflous pointer check.

Use a cut down version of the work in progress move library to implement move
semantics on more compilers. Unfortunately the move constructor with allocator
isn't really practical at the moment, since in the case where the container
can't be moved, and the allocators aren't equal it will copy the container
twice.
