When a PDCH is disabled all resources should be freed. This is
currently not possible as the PDCH does not know where it belongs
to. On top of that the list (and other resources) should be
properly initialized on construction so that disable() is idempotent
and does not check if it was disabled. During the re-factoring I
noticed that during a sysmobts re-start some resources are not
freed. I left a warning in the code to resolve this issue later.
There was no difference but there is no point in poking in the
internals of the tbf, pdch and trx from various places. Information
hiding has a real purpose, e.g. compare with reading "the mythical
man month".
