Subject: 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.
