This removes some unsafe code, improving the interface so that it cannot
be misused (e.g. previously, different Vec<u8> instances could be passed
to fdt functions that did not validate the contents).
The new implementation also adds some extra error checking to catch
invalid string values in all API entry points that accept strings, as
well as out-of-order node nesting that would result in DTB data that did
not conform to the spec.

With this, Android can access files from host in early stage so
it can import properties from host. To avoid introduce more
command line flags, just reuse the fstab file: any entries begin
with #dt-vendor means a host side file need to be put in device tree.
