Both Synch. sequence and Training sequence are basically the same thing,
only the length is different. I guess this is why 3GPP TS 45.002 names
them differently. Let's mention them both to avoid confusion.

This has been the port used historically in most existing deployments,
and it's the one already documented in the osmux section of user
manuals.

How and when socket statistics are generated is not immediately obvious.
Lets add some documentation about it.

Remove this workaround, as we are not building for debian 8 anymore.

Introduce a new flag (1-bit field) indicating whether a VAMOS PDU
is for a _primary_ ('0'B) or for a _shadow_ ('1'B) timeslot. This
field shall be present only in the Uplink VAMOS PDUs, which unlike
the Downlink (AQPSK) PDUs are sent separately. This will simplify
routing of such PDUs in osmo-bts.

It's unclear why it was removed in I5fe6263ac666e41cbe34407f09e9023aafa57d2c
when common/chapters/glossary.adoc of this very same repository uses it.

We should use service-aliases and not the primary host name, as
that makes migration between machines hard.

This field will also appear in TRXDv2 packet diagrams, in several
places. Let's rename it to 'RFU', because it's actually something
that may want to use in the future, rather than just padding.

* Add 'referred to as NOPE.ind', this is how we usueally call it;
* Change 'IDLE / NOPE' to 'NOPE / IDLE', because:
** there can be 'IDLE TDMA frame', but not 'NOPE frame';
* Avoid using 'high' and 'low' terms for bit values.
* Introduce and use macros for '0'B and '1'B.

Merge gb-variants.adoc into gb-ns2.adoc
Add a general overview of the internal structure which is also used
by the vty.
Move the configuration into a seperate adoc to allow the PCU manual to skip
the part which doesn't apply for it.
Copy the timer configuration into gb.adoc to allow document newer
timers. All users of the NS2 code will use the timer sub-chapter.

This file is included by 'osmux.adoc', so we end up including it
twice in 'test-usermanual.adoc'. This makes xsltproc complain:
/build/tests/test-usermanual.xml:643: element section:
validity error : ID mgcp-extension-osmux already defined
and sometimes causes sporadic build failures. Exclude it.

The way how the indicated Training Sequence Code is supposed to be
used by the BTS is behind the scope of this protocol specification.

AQPSK is used exclusively on Downlink in VAMOS mode. An AQPSK burst
is basically a combination of two Normal Bursts. Each of these two
bursts has the same length as defined for GMSK, while both must be
using Training Sequences from different sets.
Four different sets are defined in 3GPP 45.002, section 5.2.3.1.
Therefore we need *two* bits to encode all possible values. Let's
rearrange the existing combinations and use '11XX'B for AQPSK. The
old combination '011X'B becomes reserved and can be re-purposed.
This change is considered to be safe, given that no implementations
are known to support AQPSK at the moment of making this change.
