The in-kernel ioctl code creates a raw# device on-demand. udev will create
the /dev/raw/raw# file when the device is created automatically.
The current raw userspace code wants to stat the file before using it,
which is unnecessary for setting up the raw device.
This patch stats the file only when query() is called as a singleton, and
it's doubtful it's needed even there. I modified as little code as I could,
though.

- add NLS stuff]

The raw devices are in the raw/ subdirectory. It makes sense to use
the same subdirectory also for the control file. The old /dev/rawctl
is also supported as a fallback.
The #ifdef OLD_RAW_DEVS (/dev/raw<N>) is unsupported from now.

The raw0 is rawctl and cannot be used as a normal raw device. The patch
also enlarge range of <N> for raw<N> and improve the query mode.
