This could fix a problem where the client incorrectly decides to delete
local data.
Previously any sqlite3_step() return value that wasn't SQLITE_ROW would
be interpreted as "there's no more data here". Thus an sqlite error at a
bad time could cause the remote discovery to fail to read an unchanged
subtree from the database. These files would then be deleted locally.
With this change sqlite errors from sqlite3_step are detected and
logged. For the particular case of SyncJournalDb::getFilesBelowPath()
the error will now be propagated and the sync run will fail instead of
performing spurious deletes.
Note that many other database functions still don't distinguish
not-found from error cases. Most of them won't have as severe effects on
affected sync runs though.
Remove all configure_files:
- Move all tests to cpp files
- Use the QTEST_MAIN macro instead of a generated main.cpp
- Include test*.moc in the cpp to let CMAKE_AUTOMOC call moc
- Pass info through add_definitions instead of generating oc_bin.h with them
This makes sure that build errors points to the original test source
file instead of the generated one in the build directory to be able to
jump and fix errors directly from the IDE's error pane.
