rtl818x_pci: add RSSI information for rtl8187SE

This patch makes the driver to report signal strength information
to mac80211 for rtl8187se boards.

It differs from my previous RFT patch:
http://marc.info/?l=linux-wireless&m=140155388332534&w=2
because:
- I have now a working rtl8187se card, so I could serve my RFT by myself. :)
- CCK measurement code has changed a bit, but it does basically the same things.
- OFDM measurement method is changed because the older method reported incorrect
  measures, at least for signals stronger than -40dBm).

CCK measurement seems quite good. OFDM seems less accurate, but this is the
same as the "reference" staging driver dose. I wanted not to change things just
to make measures of _one_ (my) card a bit more close to what _I_ (in my setup)
expected..

IMHO results are still good enough to justify reporting signal in dBm rather than in
"unspecified" units, so this is what this patch actually does.

Results of my tests with a working rtl8187se card connected with coaxes and
various RF attenuators to my AP are:

Input (approx) | CCK meas | OFDM meas
--------------------------------------
      -30dBm   |  -32dBm  |  -31dBm
      -40dBm   |  -40dBm  |  -41dBm
      -50dBm   |  -50dBm  |  -55dBm
      -60dBm   |  -59dBm  |  -63dBm
      -70dBm   |  -69dBm  |  -73dBm
      -80dBm   |  -79dBm  |  -83dBm

Also some real-field tests has been done (no coax, packets in the air) for the CCK
measure method, and they resulted in reasonable values.

ieee802154: 6lowpan: ensure header compression does not corrupt ipv6 header

The 6lowpan ipv6 header compression was causing problems for other interfaces
that expected a ipv6 header to still be in place, as we were replacing the
ipv6 header with a compressed version. This happened if you sent a packet to a
multicast address as the packet would be output on 802.15.4, ethernet, and also
be sent to the loopback interface. The skb data was shared between these
interfaces so all interfaces ended up with a compressed ipv6 header.

The solution is to ensure that before we do any header compression we are not
sharing the skb or skb data with any other interface. If we are then we must
take a copy of the skb and skb data before modifying the ipv6 header.
The only place we can copy the skb is inside the xmit function so we don't
leave dangling references to skb.

This patch moves all the header compression to inside the xmit function. Very
little code has been changed it has mostly been moved from lowpan_header_create
to lowpan_xmit. At the top of the xmit function we now check if the skb is
shared and if so copy it. In lowpan_header_create all we do now is store the
source and destination addresses for use later when we compress the header.

The scheduler is a HW sub-block that directs the work of the Flow
Handler by issuing requests for frame transfers, specifying source

initialising and maintaining the hardware registers. This is
