switch from libdbi to lbsqlite3

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.
