The choice of libdbi was one of the biggest early mistakes in (back
then) OpenBSC development. A database abstraction library that
prevents you from using proper prepared statements. Let's finally
abandon it and use sqlite3 directly, just like we do in osmo-hlr.
I decided to remove the database migration code as it would be relatively
cumbersome to port all of it to direct sqlite3 with prepared statements,
and it is prone to introduction of all kinds of errors. Since we don't
have a body of older database files and comprehensive migration tests,
it is safer to not offer migration code of uncertain quality. The last
schema revision (5) was introduced 5 years ago in 2017 (osmo-msc
v1.1.0), so it is considered an exceptionally rare case. People can
install osmo-msc 1.1.0 through 1.8.0 to upgrade to v5 before using
this new 'direct sqlite3' version of osmo-msc.

Looking at 'perf top' of osmo-msc under load shows that there's a
significant amount of time spent in terms of locking (mutex,...)
which is useless as osmo-msc is a single-threaded application.
Unfortunately libdbi doesn't provide a mechanism to perform
sqlite3_config(), so we have to do it directly here, introducing an
explicit build-time dependency (and linkage) to libsqlite3.

Add the missing runtime dependency to the sqlite3 driver of libdbd.
The library does not provide a pkgconfig file, so using "pkgconfig(...)"
as done in the BuildRequires is not possible. Write both the OpenSUSE
and CentOS name with an if..else.
Fixes:
<0009> db.c:648 Failed to create database connection to sqlite3 db 'sms.db';
Is the sqlite3 database driver for libdbi installed on this system?

The SPEC file already included a build dependency to libsmpp34, but
then the compilation of osmo-msc didn't actually pass --enable-smpp
along, resulting in binaries without SMPP support - unlike the Debian
binaries, which do contain that part.

Remove OpenSUSE bug report link, set version to @VERSION@, make it build
with CentOS 8 etc.
