rsl: Introduce new osmocom extension IE RSL_IE_OSMO_ABS_FRAME_NUMBER 

This will be used in RSLms to provide Absolute Frame Number information
of the primitive indications being sent to upper layers, so that it's
possible to track GSM time in the upper layers.
The existing RSL_IE_FRAME_NUMBER and RSL_IE_STARTNG_TIME cannot be used
there, since those are 16bit fields containing Relative FN values.
