libctf: drop error-prone ctf_strerror
This utility function is almost useless (all it does is casts the result
of a strerror) but has a seriously confusing name. Over and over again
I have accidentally called it instead of ctf_errmsg, and hidden a
time-bomb for myself in a hard-to-test error-handling path: since
ctf_strerror is just a strerror wrapper, it cannot handle CTF errnos,
unlike ctf_errmsg. It's astonishingly lucky that none of these errors
have crept into any commits to date.
Fuse it into ctf_errmsg and drop it.
libctf/
* ctf-impl.h (ctf_strerror): Delete.
* ctf-subr.c (ctf_strerror): Likewise.
* ctf-error.c (ctf_errmsg): Stop using ctf_strerror: just use
strerror directly.
