    libctf: dump header offsets into the debugging output
    
    This is an essential first piece of info needed to debug both libctf
    writing and reading problems, and we weren't recording it anywhere!
    
    (This is a short-term fix: fairly soon, we will record all of this in a
    form that outlives ctf_bufopen, and then ctf_dump() will be able to dump
    it like it can everything else.)
    
    libctf/
    	* ctf-open.c (ctf_bufopen): Dump header offsets into the debugging
    	output.
