Provide access to dlopen.

* configure: New test for dlopen.

* lib.c (cptr_equal_op): Function renamed to
cobj_equal_handle_op, to reflect what it's really
doing; it is not specifically to cptr objects.
Also changed from static to extern.
(cptr_ops): Follow rename.

* lib.h (cobj_equal_handle_op): Declared.

* sysif.c (cptr_dl_destroy_op): New static function.
(dlopen_wrap, dlclose_wrap, dlsym_wrap, dlvsym_wrap): New
static functions.
(sysif_init): Register new intrinsic functions dlopen,
dlclose, dlsym, dlvsym. New variables rtld-lazy, rtld-now,
rtld-global, rtld-local, rtld-nodelete, rtld-noload,
rtld-deepbind.
