libctf: make debugging easier when hash debugging is on

Arrange that when hash debugging is on, ctf_set_errno and
ctf_set_typed_errno become real functions: renumber the error values (now we
have changed soname and can do that) so that ECTF_NEXT_END is first, and
thus obviously number 1000, so it's easy to drop a breakpoint condition
on err != 1000 to get all real non-end-of-iteration errors even in the
absence of macro debug info.
