This allows to have a device table for all directories/files and
another device table for the device files themselves. Both are needed
for static /dev, but only the first one is needed when
devtmpfs/mdev/udev are used.
We take this opportunity to move the documentation of the device table
format in a common location, package/makedevs/README.

There's no real reason to sync after creating the device nodes,
and it slows down the file system image creating quite a lot on
busy systems, so get rid of it.

The makedevs script did not always generate the requested set of device names / minor number series.
* If start != 0, then requesting (count) devices would generate only (count - start)
* If start != 0 && increment != 1, then requesting minors starting with (minor) would generate minors starting with (minor + (start * (increment - 1)))
This patch fixes the code and updates the usage text with extra examples.
