Pau Espin f320ac5841 audio: Introduce SAPI v1 with unordered RFCI support
This commit introduces support for the new llsk_audio SAPI v1.
This new version is almost the same as v0, with the exception that
primitive <REQUEST,HNB_AUDIO_PRIM_CONN_ESTABLISH> wins an extra field
appended at the end:
"""
uint8_t rfci[HNB_MAX_RFCIS]; /* values range 6 bits */
"""

This allows lowerlayers to provide an unordered array of RFCIs, which
was seen may happen under some conditions. For instance:
"""
rfci[HNB_MAX_RFCIS] = { 2, 3, 1};
[0] RFCI 2
[1] RFCI 3
[2] RFCI 1
"""

OsmoHNodeB still supports v0 if the lowerlayer asks for it, and will
continue having the exact behavior as before in this case (using
position in the array as RFCI). Hence, no compatibility breakage occurs
in this patch. New clients, on the other hand, can provide the extra
information by announcing V1 support during version negotiation at
startup.

osmo-hnodeb - Osmocom hNodeB Implementation

This repository contains a C-language implementation of a 3G Home NodeB (hNodeB). It is part of the Osmocom Open Source Mobile Communications project.

You can use it to interface Iuh-speaking Home NodeB Gateway (HNB-GW), such as osmo-hnbgw.

IMPORTANT: This is a first step towards implementing a minimal hNodeB upper layer part, mainly handling HNBAP/RUA/RANAP messages on the Iuh interface. This is not expected to be a full / usable hNodeB anytime soon [if ever].
