sysfs needs to be available before we can check interfaces. On udev
systems this was not a problem, but with mdev/static-dev, there is no
other need for sysfs until later in the init.

On linux systems running >=linux-3.2, the /proc/net/dev file cannot be
relied on to show the order network interfaces were added to the system.
Also, there is currently a bug in the implementation of the seek call
for this file which can cause a system to go into an infinite loop.
This commit changes the _ifindex function to retreive the value of
/sys/class/net/${IFACE}/ifindex and use that value instead of attempting
to calculate one from the interface's position in /proc/net/dev.

The location of the ifconfig binary has changed in
net-tools-1.60_p20120127084908, and if we do not check both locations
for it, the user will get errors like:
_is_wireless: command not found
_exists: command not found

This reverts commit f583030e3c.
The previous commit did not account for the case of not having iproute2
installed.

Provide consistent methods using iproute2/ifconfig to check operational
and administrative up/down state of interfaces. This is not the same as
ethtool's "Link detected" field, which is the state of the layer 2
medium.
