fixed bug in ulsch_scheduler

ue runs again on exmimo2 (but does not connect yet) added openair0_reconfig function in exmimo2 library added sensing thread for SPECTRA in lte-softmodem (protected by #ifdef SPECTRA) added Rohde and Schwarz client git-svn-id: http://svn.eurecom.fr/openair4G/trunk@5780 818b1a75-f10b-46b9-bf7c-635c3b92a50f
