netdev-linux: Cache flags using netlink.
		
Before this patch, every request for a 'netdev_dev''s flags
required an ioctl call.  This occurred every time
netdev_get_carrier() was called, which theoretically was very often
if there were a large number of devices.  We were already using
netlink to keep track of the IFF_RUNNING flag. This patch
generalizes the code to keep track of all flags using the same
netlink code.

netdev-linux: Get carrier from ioctl instead of sysfs.
		
When a netdev Linux device is created or its netlink cache is
invalidate, it needs an alternative method to update the its
carrier status.  Previous patches retrieved this information from a
sysfs file.  This patch switches to ioctl which is significantly
simpler, and likely quite a bit faster as well.
