The C Binder driver exposes messages over netlink when transactions
fail, so that a userpace daemon can respond to processes with many
failing transactions.

Ugh, now I regret letting binder use Netlink. Should have seen this
coming :/

To be honest, I'm not entirely happy with what Binder is using netlink
for either, but it is what it is.

This patch series adds netlink support from Rust, then implements an
equivalent API in Rust Binder.

As Binder only uses broadcast messages, I did not add support for other
kinds of messages.

Please no duplication of existing code in Rust.

The plan is certainly to get rid of C Binder, but it was unfortunately
not possible to get there without a transition period.
