Commit status quo (pending cleanup of the debug and experimental code that I added during the last week)
Change freertos code to not mask FIQ, this finally makes the FIQ working (with approx 700ns +/- 100ns latency; yeah!) and therefore reception starts working
Change to two times oversampling (keep four times oversampling code ifdef'd, extract all the magical values to a header file) because at four times oversampling every other sample is very close to
a possible data edge and therefore not reliable
