That's necessary for SGSN to properly handle BSS response to reset
procedure initiated by SGSN (foe example via 'bssgp bvc nsei 101 bvci 0
reset' command).
According to 3GPP TS 48.018 §8.4 "after performing the BVC Reset
procedure all affected BVCs are assumed to be unblocked at the SGSN" so
there's no need in any special handling.

Clear out the EXCLUDE tag to not exclude anything.
Tried to add API doc to gsm/protocol/gsm_08_08.h and after a long time found
out why they are not appearing in the API doc.
The original reason to exclude these files was that we were not going to
copy-paste descriptions from the 3GPP specs. Nevertheless, for an API doc
reader it is helpful if all data structures are listed and linked.

If we pass CFLAGS params to configure, then the CFLAGS set inside
configure.ac are not applied and the build fails if -Werror is enabled
because then BUILDING_LIBOSMOCORE is not defined.
Seeing the following output at configure time in FreeBSD build:

Our current build server uses clang-3.4.1 and FreeBSD10.3, and
AddressSanitizer support is not good yet on those versions, triggering
some link issues when it is enabled.
I tested using newer clang 3.7.1 in the same FreeBSD version but another
compiler error related to __builtin_cpu_supports is triggered.
Conclusion: Explicitly disable AddressSanitizer until we move to
FreeBSD11 with clang 3.8. Before this commit, AddressSanitizer was
implicitly disabled due to a shell compatibility issue which is fixed
in next commit in the series, thus we need to explicitly disable it here.

Recent commit 884ba0f2bc adds function
gsm0808_chan_type_to_speech_codec() but adds a mismatching name in
libosmogsm.map. openbsc.git's aoip branch can't build with this.
This must have been an on-the-fly rename that wasn't properly tested. Always
test your patches!

Considering the various styles and implications found in the sources, edit
scores of files to follow the same API doc guidelines around the doxygen
grouping and the \file tag.
Many files now show a short description in the generated API doc that was so
far only available as C comment.
The guidelines and reasoning behind it is documented at
https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation
In some instances, remove file comments and add to the corresponding group
instead, to be shared among several files (e.g. bitvec).

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

speech codec type.

Allocation of a new memory is an expensive operation, which

we need, or in order to decrease total memory usage.
The trellis struct wasn't require dynamic allocation itself,

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().
