doxygen: Tried to fix documentation (sicslowpan-doc.txt, uip6-doc.txt)

Browse Source 
This commit tries to also fix the documentations of sicslowpan and
uip6 to reflect the current code state. I’m not sure if everything
makes sense.

sicslowpan: There are still some references to HC01, can this be
replaced by HC06?

uip6: Section about timers has changed, is this correct?

Doxyfile: The documentations reference static functions, to link to 
them correctly EXTRACT_STATIC = YES is needed.



Congratulations you fixed 134 of doxygen's warnings (old: 134 new: 0).
