    gsm0808: add function to extrapolate speech codec
    
    The contents of the speech codec element (struct gsm0808_speech_codec),
    that is also used in the speech codec list element (struct
    gsm0808_speech_codec_list) can be extrapolated directly from the
    permitted speech parameter in the channel type field (struct
    gsm0808_channel_type) when full AoIP with compressed speech via
    RTP/UDP/IP is assumed and when the codec configuration on the air
    interface exactly matches the codec configuration on the IP backhaul.
    
    This patch adds a function that can be used as a helper to fill
    out spech codec fields by only giving a permitted speech parameter
    as input.

    gsm0808: add function to translate perm speech to speech codec type
    
    The permitted speech field used in channel type element (struct
    gsm0808_channel_type) uses a different representation as
    the type field in the speech codec element (struct
    gsm0808_speech_codec)
    
    This patch adds a function to convert from permitted speech to
    speech codec type.

    gsm0808: add default speech codec configuration
    
    In an AoIP scenario, the speech codec list field specifies the
    codecs used in the RTP interface. This patch adds a table
    with default codec configurations that match the codec
    configurations that are also used on the air interface.

    gsm0808: fix AoIP speech codec element parser/generator
    
    The implementation of the parser/generator for the speech codec
    information element slightly wrong, making it impossible to use
    it properly.
    
    (See also: 3GPP TS 48.008, 3.2.2.103)

    gsm0808: add speech codec type constants
    
    The codec type to be set in member type in struct gsm0808_speech_codec
    has its own coding scheme to reference the used codec types. This patch
    declares an enum with valid speech codec types.

    gsm0808: fixup length check of the element decoder functions
    
    The length check of the decoder functions is not entirely
    correct. The check also checks for values below zero,
    which does not make sense, since the length is encoded
    as uint8_t.
    
    For some elements a minimum length is known (in most cases
    this is 1, so checking for zero is sufficient but in some
    cases (e.g. channel type) the spec mentions a minimum and
    maximum length. This is now also reflected in the code.

    gsm0808: update permitted speech constants
    
    3GPP TS 48.008 specifies two new half rate speech modes and two
    new full rate speech modes. This patch adds the matching constants
    to enum gsm0808_permitted_speech
