[patch] Improving shared_ptr for C++0x

[Jonathan Wakely]

This patch adds move semantics and the features from N2351.  I believe
this brings GCC's shared_ptr in line with the latest C++ working
paper.

New tests and docs on the implementation choices are included. There
are a few places where further work could be done, see the new HTML
file for details. That doc is also available at
http://www.kayari.org/doc/c++/shared_ptr.html to save you reading the
HTML. I haven't linked to the new doc from any existing pages yet as
the C++0x status is still experimental and I don't know where these
sort of implementation notes will fit in Benjamin's new doc plan.

Tested x86_64/linux, OK for mainline?
