Introduce die_errno() that appends strerror(errno) to die()
There are many calls to die() that do, or should, report strerror(errno) to indicate how the syscall they guard failed. Introduce a small helper function for this case. Note: - POSIX says vsnprintf can modify errno in some unlikely cases, so we have to use errno early. - We take some care to pass the original format to die_routine(), in case someone wants to call die_errno() with custom format characters.
