Added needed include: see http://article.gmane.org/gmane.comp.lib.boost.devel/163941.
Copy hash library from 1.34.1 over trunk.

For the first merge with the release branch, I only want to include some of the
changes I've been working on (fixes and some trivial changes), so I'm starting
again from 1.34.1.
Update the copyright in the hash library.
Fixes #1243
Fix for gcc -Wundef warnings. See http://svn.boost.org/trac/boost/ticket/1130.
