The sample configs supplied within the doc/trx directory set the
rx-gain parameter to 1. A low value like this may cause a noticeable
degration of rx performance (For an USRP B200 an rx-gain of 38dbm is
recommended). Lets remove this seting from the sample configuration to
allow the default settings in osmo-trx to be applied.

The radio link quality is defined by C/I (Carrier-to-Interference
ratio), which is computed from the training sequence of each
received burst, by comparing the "ideal" training sequence with
the actual (received) one.
Link quality measurements are used by L1SAP to filter out "ghost"
Access Bursts, and by the link quality adaptation algorithms. One
can define minimum link quality values using the VTY interface.
On the VTY interface we expect integer C/I values in centiBels
(cB, 10e-2 B), while the internal structures are using float
values in deciBels (dB, 10e-1 B). Some PHYs (sysmo, octphy,
oc2g, and litecell15) expose C/I measurements in deciBels,
while on the L1SAP interface we finally send then in centiBels.
Let's avoid this confusion and stick to a single format, that
will be used by the internal logic of OsmoBTS - integer values
(int16_t) in centiBels. This will give us the range of:
-32768 .. 32767 centiBels, or
-3276.8 .. 3276.7 deciBels,
which is certainly sufficient.

This will generate the VTY/counter documentation for osmo-bts-virtual so
it will be missing documentation for device-specific commands/counters.

This reverts commit ad7b8bee71.
Unfortunately the osmo-gsm-manuals-dev package isn't working properly
yet, therefore osmo-bts fails to build on nightly OBS now. My apologies
for not testing enough in my own OBS namespace, before merging. I'll do
that in the future. I'm reverting the patch now, so osmo-bts isn't
missing from the nightly repository until I've fixed the
osmo-gsm-manuals package.

Moved to doc/manuals/, with full commit history, in preceding merge commit.
Now incorporate in the build system.
Build with:
$ autoreconf -fi
$ ./configure --enable-manuals
$ make
Shared files from osmo-gsm-manuals.git are found automatically if
- the repository is checked out in ../osmo-gsm-manuals; or
- if it osmo-gsm-manuals was installed with "make install"; or
- OSMO_GSM_MANUALS_DIR is set.

This chapter defines the protocol used between osmo-trx and
osmo-bts-trx.
Most of the text comes originally from osmo-trx.git/README, as it's the
only known documentation of the protocol other than the code itself.

The initial goal was to make sure we don't have overall FORCE rules causing
unnecessary rebuilds -- annoying while writing documentation. As I looked
through possible dependencies, I finally understood what's going on here.
Remove code dup and nicely sort which belongs where in build/Makefile.*.inc. In
each, describe in a top comment how to use it, and also unify how they are
used:
- Rename Makefile.inc to Makefile.docbook.inc and refactor
- Add Makefile.vty-reference.inc
- Add Makefile.common.inc
Make sure that we accurately pick up all dependencies.
Drop use of the macro called 'command', that silenced the actual command lines
invoked and replaced them with short strings: it obscures what is actually
going on and makes the Makefiles hard to read and understand.
Each manual's makefile is greatly reduced to few definitions and a Makefile
include, e.g. one for asciidoc, one for VTY reference.
Move common/bsc_vty_additions.xml to OsmoBSC/vty/libbsc_vty_additions.xml, link
from OsmoNITB. It applies only to OsmoBSC and OsmoNITB.
Add a script that combines a VTY reference file with *all* additions files
found in a manual's vty/ dir. Call this from Makefile.vty-reference.inc.

Below commit accidentally removed osmobts-abis.pdf from the Makefile entirely.
The pdf was re-added, but the dependencies are still missing, so that
osmobts-abis.pdf is not rebuilt when abis/* is newer. Fix that.
