Added support for binding to local IP addresses in ogs_sctp_client and
ogs_sctp_server, and correct SGsAP configuration
Implemented the ability to bind to one or multiple local IP addresses using
`sctp_bindx()` in both the `ogs_sctp_client()` and `ogs_sctp_server()` APIs.
Users can now specify local addresses in the configuration files under the new
`local_addresses` field, reducing unnecessary complexity and signaling caused
by binding to `ANY_ADDR`.
This update addresses issue https://osmocom.org/issues/6509 by ensuring
correct operation in multi-interface and complex networking setups.
Additionally, corrected the `sgsap` configuration by changing it
from `server` to `client`, and added support for specifying `local_addresses`
for local binding as follows:
```
sgsap:
client:
- address: msc.open5gs.org # SCTP server address configured on the MSC/VL
local_address: 127.0.0.2 # SCTP local IP addresses to be bound in the M
```
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.
