Subject: configure: verify header presence against sources

in addition to the actual library resolution, also resolve the headers
belonging to the library, to validate the include path, and possibly
ensure that the right version of the library is present.

the "include" entries were moved out of the "test" objects, and renamed
to "headers". this cleanly permits libraries without compile tests.

the headers were not put into the sources, because the variance among
the includes is generally orthogonal to the variance among the
libraries.

note that this - like the library resolution - provides no support for
darwin frameworks. consequently, the opengl libraries are excluded from
the conversion on darwin.

similarly, wasm is excluded (centrally), because emcc is magic and would
need advanced wizardry to be dealt with.
