So far, we used quarter-bits across the L1SAP between the hardware/PHY
specific part of OsmoBTS and the common part. In order to increase
the resolution, let's add fields/members for 1/256th bit.
In order to keep ABI and API compatibility, we use a union around the
old and new values, so old code will still compile + work withe new
libosmocore.

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.

The distribution of the channel measurement calculations over
multiple timeslots (continous calculation) requires to keep
track of the frame number in struct info_meas_ind_param

Extend struct ph_tch_param with Marker bit from RTP header to indicate
speech onset in case of DTX.

We already have RSSI parameter in PH-DATA. Add other measurement
information (BER, BTO, Link Quality).

Parameters are added to the structure ph_rach_ind_param to
differentiate the type of RACH received from Layer 1. This is to
further support the 11 bit RACH.

Previously the presence of header and data blocks were communicated
in-band which decreases code readability and makes it unnecessary hard
to add support for new hardware.
Note: OsmoBTS have to be modified to take advantage of extended
ph_data_param structure.
In order to control layer 1 via primitives, MPH primitives are required.
There is only one (MPH-INFO) primitive defined in TS 04.04 for all control
and measurement functions. A type identifier inside this primitive is used
to differentiate between different functions.
The TCH primitives are used to carry traffic. TCH primitives carry voice
or data traffic, whereas PH-DATA primitives carry FACCH data.
PH_RTS and TCH_RTS (ready-to-send) primitives are used to poll requests
from upper layers.
