Revert "Revert "Add NETLINK_ROUTE processing to the netlink client code, so that Ethernet""

This reverts commit 1d504eeb50d980c222572629383bb76315f32ca0.

Bring back the changes from Stan Chesnutt regarding adding NETLINK_ROUTE
processing.  The original commit message description was:

    Add NETLINK_ROUTE processing to the netlink client code, so that Ethernet
    physical-layer up/down events can be tracked.  Upper layers will use these
    events to enable/disable Ethernet connectivity.

The original change was reverted due to an incompatiblity with Motorola's
ril.so binary.  I'll submit a patch to workaround that incompatiblity
separately.
