tools/xenstore: Check the format printf for xprintf() and barf{,_perror}()

Allow GCC to analyze the format printf for xprintf() and
barf{,_perror}().

Take the opportunity to define __noreturn to make the prototype for
barf{,_perror})() easier to read.

Also document why 'extern' is used for xprintf().
