libnm,platform: fix range for "weight" property of next hops for routes 
In kernel, the valid range for the weight is 1-256 (on netlink this is
expressed as u8 in rtnh_hops, ranging 0-255).

We need an additional value, to represent

- unset weight, for non-ECMP routes in kernel.

- in libnm API, to express routes that should not be merged as ECMP
  routes (the default).

Extend the type in NMPlatformIP4Route.weight to u16, and fix the code
for the special handling of the numeric range.

Also the libnm API needs to change. Modify the type of the attribute on
D-Bus from "b" to "u", to use a 32 bit integer. We use 32 bit, because
we already have common code to handle 32 bit unsigned integers, despite
only requiring 257 values. It seems better to stick to a few data types
(u32) instead of introducing more, only because the range is limited.

libnm-core-impl

NetworkManager provides a client library libnm. NetworkManager core does not (dynamically) link against all of libnm. Instead, it statically links against a part of it. That part is the static helper library libnm-core-impl.

libnm-core-impl implements (and provides) the API from libnm-core-public, which is part of the public API of libnm. In this form, libnm-core-impl is part of the implementation of libnm. It also implements (and provides) an internal API libnm-core-intern which can only be used by those who link statically against libnm-core-impl.

Only NetworkManager core and libnm are allowed to statically link with libnm-core-impl. Consequently, only those are allowed to include libnm-core-intern.

This directory should not be added to the include search path of other components as they are only allowed to include libnm-core-public and libnm-core-intern.
