libctf, include: debuggability improvements

Browse Source 
When --enable-libctf-hash-debugging is on, make ctf_set_errno and
ctf_set_typed_errno into real functions, not inlines, so you can
drop breakpoints on them.  Since we are breaking API, also move
ECTF_NEXT_END to the start of the _CTF_ERRORS array, so you can
check for real (non-ECTF_NEXT_END) errors in breakpooints on those
functions by checking for err > 1000.
