Currently, files that omit the \file directive and all functions, enums,
structs lacking a doxygen style comment are completely missing from the doxygen
API docs.
Set EXTRACT_ALL = YES so that all files and code items are at least listed in
the doxygen API.

include/osmocom/gsm/protocol is also implicitly included in its parent dir
because of the recursive rule. Naming it again makes doxygen use it twice. It
doesn't seem to be harmful, but not needed either.

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.

Typically we don't place comments with the function declarations
in .h files. Not sure why this file has comments for each. The
API doc belongs in the .c file as proper doxygen comments,
and shouldn't be duplicated in the .h file.
In this particular case, doxygen comments are added in the
corresponding c file recently.

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 generated 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.

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.

In an AoIP scenario, the speech codec list field specifies the
codecs used in the RTP interface. This patch adds a table

configurations that are also used on the air interface.

Allocation of a new memory is an expensive operation, which
takes place when it's initially unknown, how much memory will
we need, or in order to decrease total memory usage.
The trellis struct wasn't require dynamic allocation itself,
so let's allocate one statically inside the vdecoder structure.

Currently this implementation exposes nothing than
osmo_conv_decode_acc(), so it wasn't possible to call
reset_decoder() from outside.
The method itself was used to initialize accumulated
path metrics and the starting state of encoder. Now
this code is moved to generate_trellis().
Moreover, setting accumulated path metrics inside
existing loop is a bit faster that calling memset().

According to GCC's online docs:
When an inline function is not static, then the compiler must
assume that there may be calls from other source files; since
a global symbol can be defined only once in any program, the
function must not be defined in the other source files, so the
calls therein cannot be integrated. Therefore, a non-static
inline function is always compiled on its own in the usual fashion.
There is no any (performance or size) benefit from 'inline' keyword
in this particular file, so let's replace one by 'static'.
