Embedding libltdl without the use of Libtool bootstrapping has proven... difficult. Instead, create a new simple "dl" framework. It only provides 4 functions: - open a DSO (very similar to lt_dlopenadvise()) - lookup a symbol in a previously-opened DSO (very similar to lt_dlsym()) - close a previously-opened DSO (very similar to lt_dlclose()) - iterate over all files in a directory (very similar to ld_dlforeachfile()) There will be follow-on commits with a simple dlopen-based component (nowhere near as complete/functional as libltdl, but good enough for Linux and OS X), and a libltdl-based component for all other platforms. The intent is that the dlopen-based component can be built by default in almost all cases. But if libltdl is available, that component will be built. End result: we still get DSO-based functionality by default in (almost?) all cases. Without embedding libltdl. Which is what we want.
