sd-netlink: don't export internal type-system details
The kernel bonding layer allows passing an array of ARP IP targets as bond-configuration. Due to the weird implementation of arrays in netlink (which we haven't figure out a generic way to support, yet), we usually hard-code the supported array-sizes. However, this should not be exported from sd-netlink. Instead, make sure the caller just uses it's current hack of enumerating the types, and the sd-netlink core will have it's own list of supported array-sizes (to be removed in future extensions, btw!). If either does not match, we will just return a normal error. Note that we provide 2 constants for ARP_IP_TARGETS_MAX now. However, both have very different reasons: - the constant in netdev-bond.c is used to warn the user that the given number of targets might not be supported by the kernel (even though the kernel might increase that number at _any_ time) - the constant in sd-netlink is solely used due to us missing a proper array implementation. Once that's supported in the type-system, it can be removed without notice Last but not least, this patch turns the log_error() into a log_warning(). Given that the previous condition was off-by-one, anyway, it never hit at the right time. Thus, it was probably of no real use.
