The number of active harqs is included in the UL_TTI_REQ

Browse Source 
Also, we had two heap-buffer-overflow crashes while
filling the CRC_IND and RX_IND. The corrected CALLOC
command is included in this commit as well.

Lastly, we included a better fix for handling late
DL_TTI_REQs. If the number of active harqs is larger
than the number of UCIs we have built, this is a good
indicator that the DL_TTI_REQ is late. To mitigate
problems, we will requeue the UL_TTI_REQ to when the
late DL_TTI_REQ comes in, we can handle the late
UCI that is built from it.
