imp d8b432de64 warnx: Save errno across calls that might change it.
When warn() family of functions is being used after err_set_file() has
been set to, for example, /dev/null, errno is being clobbered,
rendering it unreliable after, for example, procstat_getpathname()
when it is supposed to emit a warning. Then the errno is changed to
Inappropriate ioctl for device, destroying the original value (via
calls to fprintf()functions).
