* libguile/array-handle.c: * libguile/array-handle.h: Move some parts of unif.c and unif.h to these new files. * libguile/unif.c: * libguile/unif.h: Update includers. Since unif.h depends on the array handle type, we include array-handle.h, which also means that there will be no difference for our callers. * libguile/init.c: Call scm_init_array_handle, though it does nothing as of yet. * libguile/Makefile.am: Adapt for new files.
