Change subject: make use of OTC_GLOBAL when allocating library-internal contexts
......................................................................
make use of OTC_GLOBAL when allocating library-internal contexts
As libosmcore is now managing the global talloc contexts, there's
no point in having APIs where the user tells the library about
which talloc contexts to use for a given sub-system.
