Robert Schmidt e3747ab592 Check if Msg3 start&length can be accommodated in mixed slot 
Prior to this commit, it might happen that the gNB used TDA 0 (Start 0
len 13) for mixed slot, in which case the UE could not send msg3
(because a mixed slot has less than 13 symbols).

Robert Schmidt defc97ec16 check Msg2 allocation frame/slot in DL scheduler 
Move decision of Msg2 allocation time instant from instance we receive
RA indication (only containing preamble time information) to actual RA
scheduler (containing current DL slot time). This has the advantage:

- if Msg2 cannot be sent, we might try in a later slot
- no timing-based problems were a RACH.indication FAPI message might
  come late, we calculate a Msg2 frame/slot, but this instant has
  already passed in the DL scheduler
- no assumption about slot_ahead (an L1 constant)

The previous code calculated and verified an SSB index; I am not sure
this code is correct or used. I leave the function
ssb_index_from_prach() (hence the gcc attribute), but remove any checks.
Similarly, the beam association list might be wrong. I deleted the
corresponding code.

Cedric Roux a323195aed nr pdcp: improve readability of integrity checking 
Introduce the structure nr_pdcp_integrity_data_t and adapt code to use it.

Note: in nr_pdcp_sdu_t we keep the 'count' variable (which is also present
in nr_pdcp_integrity_data_t). They represent the same value, but 'count'
in nr_pdcp_integrity_data_t is to be specifically used for integrity while
the other one has other uses, so it's better to keep it.

Cedric Roux f85e3adc5a nrUE: bugfix/improvement in security mode handling 
The use of security_mode_completed in the PDCP entity was a hack.

Plus it was not working at all with the deregistration request
when nea2 is used, sent when doing ctrl+c in the nrUE.

So let's remove it.

And let's handle activation of integrity and ciphering more in
accordance with what 38.331 says. SecurityModeComplete has to
be sent integrity protected, but not ciphered. Only after should
the ciphering be activated. (See 38.331 5.3.4.3.)

Robert Schmidt 1e8f194d11 Only release UE in PDCP if in E1 
Explanations: see #706. TLDR: the RRC code calls nr_pdcp_remove_ue(), so
we should not call it in the E1 handler if we do not use split mode.
