Add support for modular build structure. (#24)

* Make the library modular usable.

* Switch to library requirements instead of source. As source puts extra source in install targets.

* Add missing b2 testing module import.

* Add missing import-search for cconfig/predef checks.

* Add requires-b2 check to top-level build file.

* Bump B2 require to 5.2

* Update copyright dates.

* Move inter-lib dependencies to a project variable and into the build targets.

* Update build deps.
