* Make the library modular usable. * Switch to library requirements instead of source. As source puts extra source in install targets. * Clean up build dependencies. * Remove external build references and avoid custom project loading. * Use relative paths to declare config sub-projects. * Add missing NO_LIB usage requirements. * Add missing library ref. * Add missing import-search for cconfig/predef checks. * Add requires-b2 check to top-level build file. * Update dependencies. * Bump B2 require to 5.2 * Update copyright dates. * Move inter-lib dependencies to a project variable and into the build targets. * Remove custom symbolic project names for config subprojects. And use project root relative targets. * Move private deps to the build project. * Put back default boost locale link as locale build is now fixed. * Set default address-model and architecture to avoid extra/custom detection logic. Put back missing check and config rules. * Adjust doc build to avoid boost-root references. * Fix ref to predef.jam location. * Have B2 build use same deps as CML for per-target private/public. * Add log dep to log_setup, as it's needed on some platforms. * Add boost_log_with_support target to mirror CML. * Fix platform specific winapi dependency spec.
