This commit adds initial support to encode/decode SBc-AP messages in the
form of a library, under src/sbcap/ (includes in
include/osmocom/sbcap/).
asn1c is used to generate all suport code and structures for ASN.1 APER
encoding/decoding, based on asn files obtained from 3GPP TS 29.168 and
stored under src/sbcap/asn1/.
Currently, mainstream asn1c doesn't yet support ASN.1 APER
encoding/decoding, hence mouse07410 's fork is used [1]. Furthermore,
several encdoing/decoding bugs where found during the process and fixed,
which means asn1.c git >= 30219de2d3da888b4f1eea0dd79f2a505000401a must
be used to generate proper code.
A new "make -C src/ gen" target is added which can be used to regenerate
all C code from the available ASN.1 files in src/sbcap/asn1/*.asn (after
properly setting configure.ac ASN_* variables if needed).

This is later used in cbcmsg_to_cbsp(), but only set for type
'payload_decoded' in parse_payload_decoded().

perror() appends ":" immediatelly afterwards in order to append the
error string, so having a newline breaks the format.

When receiving SMSCB_E_CBSP_DELETE_(N)ACK, smscb_message_fsm will iterate
over all peers to find out if some of them has still not ended, and in
that case delay sending an HTTP result.
However, the peer was sending the signal before moving to DELETED state,
and hence smscb_message_fsm would never send the HTTP result until T3
(T_WAIT_DELETE_ACK) would time out after it:

OsmoCBC uses libulfius, which creates its own thread(s).
Hence, we must set up osmocom logging system appropiately so that
relevant stuff is protected by locks.

log macro needs to be changed since it uses cbsp_cbc_client_name() which
accesses client->conn which is NULL in there.

There's no need to pass the specific params. Let's simply get whatever
need from the global config in the function.
This makes it easier to extend it to more params if needed.
Also, when we add SBc-AP support, the params that have to be passed to
the counter part function are different, so let's simplify param
passing here.
While at it, rename also the callback function to contain "cbsp" on it,
since it is cbsp specific.

As the peer->remote_host is initially NULL when creating a CBC peer,
the code should tolerate this. The situation arises in two cases:
* if a peer is created by VTY but without any subequent 'remote-ip'
statement
* if a peer is auto-created by 'unknown-peers accept'

This example is not any better than just using '-c /dev/null'.
Add some default parameters taken from 'show running-config'.

We need to use the matching enum values if we actually want to

The "required" parameter to argparse.add_subparsers() was only
added in python 3.7. However, given that it defaults to 'required'
and was always unconditionally required even in python 2.x,
we can safely remove it.
