Fix A5 description concerning A5/2 (not in use).
Fix UICC: 'Circuit Card', not 'Chip Circuit', and replace 'FIXME'.
NITB: like OsmoNITB just without Osmo, reference OsmoNITB.
Add some words/explanations (FPGA, MSC, OXCO, UICC, VTY).
Fix minor typos ('Freee', 'usees', over-eager dashes '-',
capitalisation).
Use 'an' before acronyms pronounced starting with a vocal ('S', 'M').
Use 'a' before 'U'.
Unify style:
Use semicoli ';' instead of periods '.' or commas ',' where appropriate.
Use lower case letters after semicoli.
By using the same name for the config it overwrite the one used
by the mscgen plugin. Let's avoid this and switch from svg to png
as well as the docbook classification doesn't seem to work.
The CI does not generate(?) or include the svg files in the PDF. It
is not clear why that is done if something is missing from mscgen or
from asciidoc or something else is wrong. Let's try once with the PNG
output.
This is a bit awkward, as the 'revnumber' asciidoc variable so far
doesn't seem to end up in the docbook-xml. We now put it into
'releaseinfo' which gets then put into \DBKreleeaseinfo by dblatex.

The manuals existed in different form for several years in an internal
sysmocom repository. However, since they had just recently been
converted from docboox-xml to asciidoc and all files have been
re-shuffled for enabling the public release, there's not much point in
keeping the history with git-filter-branch.
