Suggested policy for dropping C++03 support in Boost libraries

We need a policy on phasing out C++03 support in Boost.

C++03 support is holding us back. It impedes development, increases 
maintenance costs, increases dependencies, and increases compilation times.

Library authors and maintainers need to have an approved mechanism for 
dropping C++03 support in their libraries.

The suggested way forward is to allow library authors to declare C++03 
support deprecated via a notice in the documentation and a message issued at 
compile time, then be allowed to drop C++03 support no earlier than three 
Boost releases later.

For instance, a library may declare C++03 support deprecated in Boost 1.73, 
and drop it no earlier than in Boost 1.76.
