It was recently found that several IEs which were added in the header
file were not actually added to the tlv_definition, and hence the tlv
parser failed to decode them. Let's make sure we don't foget to add new
IEs in the future.

Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

This change adds new [bit-]fields in order to allow:
* selectively enabling SACCH and/or FACCH,
* setting the RxQual (BER) threshold.

Libosmocore currently does not offer any structs to encode and decode
the l1 information on RSL level and the sacch l1 header on the air
interface level. Both structs are identical but the field order in the
first octet is reversed.

Thanks to the CLI of nanoBTS, I noticed that upper and lower RxQual
thresholds are sent in wrong order. Only the little-endian variant
needs to be fixed, the big-endian one looks good.

In order to transfer an RXQUAL threshold to the BTS as well, the struct
that defines the contents of RSL_IE_OSMO_REP_ACCH_CAP needs to be
updated with a 3 bit field to contain the RXQUAL value.

The recently added IE is used to transfer a bitfield, lets add a struct

3GPP TS 24.008, section 10.5.1.7 specifies a Repeated ACCH Capability
bit in the Classmark 3 IE. Unfortunately, there is no way specified how
the Repeated ACCH feature should be controlled on RSL level. Since it is
not unusual that BTS/BSC vendors occassionally add proprietary IEs to
different RSL messages we may pick this as a solution as well and add a
propritary RSL_IE_OSMO_REP_ACCH_CAP IE, so that we can enable repeated
FACCH/SACCH on the BTS side when we send RSL CHAN ACT or RSL CHAN MODE MODIFY
messages.

We don't really *need* it in libosmocore as such, but the lack of
having all osmocom extensions listed here lead to using overlapping
definitions: 0x18 was used for dynamic PDCH on the Abis side, but also
for CBCH on the L1SAP side. Let's list them all here to increase
visibility in case anyone wants to extend this further...

This is 1:1 the result of doing
cd libosmocore
./contrib/struct_endianess.py
git commit -a
Running struct_endianess.py again should result in no changes.
That means we could include such a check in the gerrit verification job now.

It will allow to make code handling chan_nr values more easier to read
and less prone to errors.
union is used to be able to get the full octet in
case we need to pass it somewhere else or encode it.
An extra union is used in struct abis_rsl_common_hdr and others to allow
using fields directly while keeping API compatibility.

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).

Ericsson uses non standard information element tags when setting
up the SI13 system information configuration. This applies to
RSL_SYSTEM_INFO_13, which is normally 0x28, instead Ericsson
uses RSL_ERIC_SYSTEM_INFO_13, which is set to 0x0C. Furthermore,
Ericsson adds a propritary field called BCCH-Mapping, which is
tagged as 0xf2 (RSL_IE_ERIC_BCCH_MAPPING)
This patch addes these two information element tags in
gsm_08_58.h

Using the RSL_CHAN_* constants, we sometimes need to add 1 to the chan bits
to indicate e.g. the second TCH/H channel.
RSL_CHAN_NR_1 marks this lowest channel bit that needs to be added.
The name is analogous to RSL_CHAN_NR_MASK.
