Backport addition of /dev/{block,char}/maj:min symlinks from latest
udev rules; this mirrors the /sys/dev/{block,char}/maj:min symlinks
found in our current kernel.

If you have a device node, stat() it to obtain type, major and minor
and readlink /sys/dev/{block,char}/maj:min to obtain the sysfs path
of that device.

If you have a sysfs path, read the "dev" file to obtain major and minor
(it's char unless in the block subsystem), and then readlink
/dev/{block,char}/maj:min to obtain the device node.
