Merge fixes from Trunk.

Fixes #2392.

Change includes of <cmath> to <boost/config/no_tr1/config.hpp>.

Previously if Boost.TR1 was in the include path then including <cmath> pulls in all the new TR1 math functions, which in turn also requires linking to an external library. With auto-linking support this requires that library to have been built and be present in the library search path, even if the actual library under use is header only.
Add or fix svn:mime-type and svn:eol-style for several files.
