Extract Mobile Identity from encoded bytes (3GPP TS 24.008 10.5.1.4).

On failure (negative return value), mi->type == GSM_MI_TYPE_NONE, mi->string[] is all-zero and mi->tmsi == GSM_RESERVED_TMSI.

On success, mi->type reflects the decoded Mobile Identity type (GSM_MI_TYPE_IMSI, GSM_MI_TYPE_TMSI, GSM_MI_TYPE_IMEI or GSM_MI_TYPE_IMEISV).

On success, mi->string always contains a human readable representation of the Mobile Identity digits: IMSI, IMEI and IMEISV as digits like "12345678", and TMSI as "0x" and 8 hexadecimal digits like "0x1234abcd".

mi->tmsi contains the uint32_t TMSI value iff the extracted Mobile Identity was a TMSI, or GSM_RESERVED_TMSI otherwise.

Parameters

[out]	mi	Return buffer for decoded Mobile Identity.
[in]	mi_data	The encoded Mobile Identity octets.
[in]	mi_len	Number of octets in mi_data.
[in]	allow_hex	If false, hexadecimal digits (>9) result in an error return value.

Returns: 0 on success, negative on error: -EBADMSG = invalid length indication or invalid data, -EINVAL = unknown Mobile Identity type.
