Creating new queue for ul_ttis if dl_tti is late

Browse Source 
Also, this commit changes the len argument in the
pusharray32 to match the actual field type (uint16_t).
There is also simple name change from sf -> slot.
The new queueing system is not a permanent solution.
It was simply a way for us to try to handle late
dl_tti_requests. If we queue every single ul_tti_req
that we get, the queue gets full very quickly becasue
we only remove ul_ttis from the queue when a uci has
been populated with a matching sfn/sf. Because of this,
we only queue ul_ttis if we have a uci_indication
prepared already. Rarely, a dl_tti_req will arrive at
the NRUE too late, and the NRUE does not have time
to create the uci_ind so we dont process the corresponding
ul_tti. A seprate queue was made to hold all other ul_ttis
the arrive in the NRUE (this queue will continuously
get full and then emptied) but will occasionally hold
a ul_tti that corresponds to a uci that hasnt
been populated yet.
