The sysmobts uses the same OML attributes as IP.access. Because the IP.access
attribute only supports IPv4 as NSVC configuration, add an own attribute.

We have a number of library-internal static global buffers which are
mainly used for various stringification functions. This worked as
all of the related Osmocom programs were strictly single-threaded.
Let's make those buffers at least thread-local. This way every thread
gets their own set of buffers, and it's safe for multiple threads to
execute the same functions once. They're of course still not
re-entrant. If you need re-entrancy, you will need to use the _c()
or _buf() suffix version of those functions and work with your own
(stack or heap) buffers.

We have a habit of returning static buffers from some functions,
particularly when generating some kind of string values. This is
convenient in terms of memory management, but it comes at the expense
of not being thread-safe, and not allowing for two calls of the
related function within one printf() statement.
Let's introduce _c suffix versions of those functions where the
caller passes in a talloc context from which the output buffer shall
be allocated.

We have a number of static buffers in use in libosmo*. This means
the related functions are not usable in a thread-safe way. While
we so far don't have many multi-threaded programs in the osmocom
universe, the static buffers also prevent us from calling the same
e.g. string-ify function twice within a single printf() call.
Let's make sure there's an alternative function in all those cases,
where the user can pass in a caller-allocated buffer + size, and make
the 'classic' function with the static buffer a wrapper around that
_buf() variant.

This is a more modern way of printing the Abis OML Formatted Object

or prescribing the log level to be used.

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).

Especially for short descriptions, it is annoying to have to type \brief for
every single API doc.
Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes
the first sentence of an API doc as the brief description.

It's a pity that even with this patch we still are fare away from having
the whole API documented. However, at least we have a more solid
foundation. Updates not only extend the documentation, but also make
sure it is rendered properly in the doxygen HTML.

* data structure representing 3GPP TS 52.021 §9.4.62 SW Description
* function to serialize it into msgb
* function to deserialize it from buffer
* functions to extract/estimate buffer size for SW Description
* test harness (partially taken from OpenBSC)
There are several similar functions to deal with SW Description in
OpenBSC, there's also need to use similar functionality in
OsmoBTS. Hence it's better to put the code into common library with
proper tests and documentation.

Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which
makes it more clear that this is an osmcoom specific attribute.
Also, we cannot simply overload 0x01 as an already defined OML
attribute. The problem is quite simple: When we use abis_nm_att_tlvdef
during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL,
which is defined as { TLV_TYPE_FIXED, 3 }.
So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[],
which has to be patched into abis_nm_att_tlvdef[] by the means of
tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific
attributes.
I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA
specific attribues (and we might want to combine/merge the 12.21 plus
IPA plus osmocom spefici attributes)
abis_nm_pchan4chcomb will return a pchan for a given channel
combination but returned a value of the channel combination.
Fix it to return the physical channel combination.

this will avoid printing 'abis_nm.c' as the filename in the log, which
is pretty useless during debugging. We want to know where
abis_nm_debugp_foh() is being used from, not where it is implemented.
and export the underlying raw value_string arrays instead:
abis_nm_obj_class_names / abis_nm_adm_state_names.
This permits the caller to use get_string_value() as well as
get_value_string().
