The initial idletimer support required using NETLINK_IDLETIMER
netlink socket type.
Instead we now just re-use the existing KOBJECT_UEVENT socket.

Some kernels used with ICS do not have the needed modules (quota2
with NFLOG support).
For those, we just don't allow NFLOG which will cripple quota alerts.
This is a temp workaround until kernels are prebuilts.

NetlinkManager, NetlinkHandler
 . added support for netlink's NETLINK_NFLOG family used by the updated xt_quota2.
 . it pushes the event all the wait to NetworkManagementService.java
    "linit alert <alert_name> <iface_name>"

This needs:
 - new kernel with quota2 changes that support logging via NETLINK's
   NETLINK_NFLOG family.
 - BandwidthController changes that setup the alerts.
 - system core NetlinkEvent that recognizes the NFLOG messages.
 - java land NetworkManagementService changes.

The java api was there to get callbacks but the middle piece was missing.
Also has one const defined for USB control that is part of a seperate change, but no harm.
