core: backend autoconnection:

A new Connection/autoconnect_backend param can be set for a profile or component to be
started automatically with backend. This is specially useful for components, but can be
useful for client profile too (e.g. on Android we need to start profile with backend to
get notifications, this part will come with following commits).

The new Sqlite.getIndParamValues method allows to retrieve the same parameters for all
profiles.
