Document maintenance rules of `test/legacy/` content. Motivation to move the `test/legacy/` is to: * clarify status of those tests * make it easier to run tests selectively * separate new/upcoming feature-specific tests from those all-in-one tests. Other changes: Rename `gil_test_common.hpp` to `unit_test.hpp` to make it clearer it acts as `boost/test/unit_test.hpp proxy`. Remove `<include>$(BOOST_ROOT)` from `Jamfile`-s as unnecessary.
