vcd: added some more traces for PHY

Browse Source 
pdcp_thread: bugfix in init 
lte-softmodem: changed thread priority for emos and xforms, changed gains for external rf, changed compile options to O2 (now possible with dlsch_demodulation fix)
new firmware version (see changelog openair0)
dlsch_demodulation: using sse4 extract for llrs
pmi_feedback now stored independend of harq_process_id
dlsim: fixed memory leak, improved csv output, changed compile option to O2 (now possible with dlsch_demodulation fix)
removed unused files
