Sukchan Lee 2ceca49161 [MME/AMF] Fixed crash following Handover Request (#3014)
1. HandoverRequired
2. HandoverRequest
3. HandoverFailure
4. UEContextReleaseCommand
5. HandoverPreparationFailure

If UEContextReleaseComplete is not received,
the Source-UE will have the Target-UE.

6. HandoverRequired

There may be cases where the Source UE has a Target UE
from a previous HandoverRequired process. In this case,
it is recommended to force the deletion of the Target UE information
when receiving a new HandoverRequired.

Sukchan Lee 843c4950ac [ASN1C] Fixed asn1c library on 32bit (#2934)
APER encoding fails when using the asn_uint642INTEGER function on a 32-bit machine as shown below.

```C
   asn_uint642INTEGER(AMF_UE_NGAP_ID, 0xffffffff);
   ...
   aper_encode_to_buffer(...)
```

INTEGER APER encode/decode functions seem to be operating internally with long variables instead of intmax_t.
That is probably the reason of the failure.

@v0-e fixed this issues in the mouse07410/asn1c pull request.
