* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Add missing import-search for cconfig/predef checks.
* Add requires-b2 check to top-level build file.
* Bump B2 require to 5.2
* Change all <source> references to <library>.
* Update copyright dates.
* Move inter-lib dependencies to a project variable and into the build targets.
* Adjust doc build to avoid boost-root references.
* Update build deps.
* Change Boost Test build refs to work with both old and modular test lib targets.
* Adjust CI for changes to the inspect tool. Also simplify the build and test to avoid future config problems as it can mor easily adjust to future CI changes.
* Use latest CI image to get a modern C++ compiler rthat doesn't ICE, we hope.
* Current CircleCI images need sudo to install packages.
* Undo search-lib change.
