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.

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
