libctf: error handling
CTF functions return zero on success or an extended errno value which can be translated into a string via the functions in this commit. The errno numbers start at -CTF_BASE. libctf/ * ctf-error.c: New file. include/ * ctf-api.h (ctf_errno): New declaration. (ctf_errmsg): Likewise.
