Patch against SVN for packet-6lowpan.c with 112-bit context example

Initial context was just 2002:db8::/64. For the 16-bit inline decoding to work
correctly it is better if the initial context is 2002:db8::ff:fe00:0/112, since
that only leaves 16 bits to be assigned by the inline bytes. Otherwise
in-lining 16 bytes is not totally obvious how to handle, as you need to expand
16 bytes to fill the 64 bytes the context does not fill.

This patch sets the default context to that value. Not technically a bug, but
would make users understand that they should set up the maximum context length
possible.
