Harald Welte d102832d9f manual: Update statements regarding SCCPlite
SCCPlite is long supported (again) by osmo-bsc, let's remove the
outdated pointers to osmo-bsc-sccplite.

Harald Welte d6e57e3471 manual: Remove bogus "Control interface" sub-section in overview
We meanwhile have chapters about the CTRL interface protocol as well
as the auto-generated list of CTRL interface commands/values, so
let's remove the somewhat redundant information.

Harald Welte 9e276081db manual: It's not "A over SCCP" but "BSSAP over SCCP"
In GSM specs, the entire interface between two elements is designated
with some letter, like the A interface between BSC and MSC.  The
interface uses a variety of protocols stacked on each other.

In the specific case of A, there is no "A" on top of SCCP, but
there's "BSSAP" on top of SCCP.

This is followed somewhat un-orthodox by 3GPP, as "A over IP" is
a violation of that principle.  It should have been called "A utilizing
IP", "A based on IP", "A with IP" or something the like.

In any case, at no point do the specs ever claim that "A" is stacked
on top of SCCP, so let's fix this.

Harald Welte 75c0e08acc initial checkin of manuals to public repo
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.
