wpan-tools: new netlink interfaces calls

Hi all,

this patch series adds support for new netlink interfaces. For all new users on this mailinglist. This is the new userspace tool for the wpan rework [0] branch.

I removed the mib lock in the rework. Now you can only set the pan_id or short address (don't implement the setting of short address now) when the netdevice is _down_.

Then we don't need the the mib lock anymore. It's protected by RTNL if netdevice is down. When it's up it's a read only variable and we can use the variable in hot path like tx/rx without locking. (This is like setting and use of dev_addr of an netdev device).

I disabled the af802154 and security layer for now, but I will add this later at the end of the rework.

I also detected that our cca_mode handling is a driver specific netlink call. This is... not good. :-) And this is the current mainline behaviour...

In the rework I added enums for the 802.15.4 CCA_MODE numbers and now the at86rf231 makes a mapping from 802.15.4 specifc CCA_MODE to driver cca_mode( which is the register value).

I need to begin to write more text about the new behaviour, is there anybody outside who already test something?

We don't have the multiple phy layer, I dropped them. This was needed for the channel hoping. We need some new idea to provide a channel hoping logic, or simple but the logic for this in userspace. (You can change the channel while netdev is up).

There are several other netlink interfaces (setting short_address,setting energy detection value of phy)

The energy detection level is not part of the 802.15.4 pib, so this will be a direct call to the driver (not saving any value of this in the pib).

changes since v2:
- remove stolen LGPL code and reimplement a own header for unsupported netlink attributes of the netlink library. Maybe somebody should add it to netlink...
