compat-wireless: split patches/01-netdev.patch up

This splits up patches/01-netdev.patch into the following
set of patches:

patches/0001-netdev_ops.patch
patches/0002-net-misc.patch
patches/0003-netdev-needed_headroom_tailroom.patch
patches/0004-wext-namespace.patch

This isolates the network device operations infrastructure
into a separate file to show one collateral evolution [0].
The next objective will be to extract SmPL out of the patch
patches/0001-netdev_ops.patch. If we can extract SmPL [1] out
of it, with the help of compat as a backend store to help
us backport the work required, we could automatically backport
this collateral evolution to any network driver. Backporting
this specific collateral evolution then on compat-wireless
would simply require adding the driver's directory to be
copied into the framework, a one line change.

If we keep doing this for more collateral evolutions the
implications are the ability to enhance automatically
backporting even more collateral evolutions and therefore
drivers.
