[hopping] Rework generation of Cell/Mobile Allocation

Calculating the Cell Allocation (basically a bit-vector of all the
frequencies allocated to a cell) on the OML link establishment has
several downsides and potential problems:

  * Theoretically, more than 64 ARFCNs can be allocated for a cell
    via the VTY interface.  The problem here is that the Mobile
    Allocation IE cannot contain more than 64 channels.

  * The BSC's operator will neither be warned by the interactive
    VTY shell during configuration, nor during the startup.

  * The BSC will accept such a configuration, but then will be
    unable to encode the Mobile Allocation IEs at run-time.

This change aims to improve the situation by separating part of
the logic from generate_cell_chan_list(), and invoking this
part directly from the VTY commands.  This way it will become
impossible to configure more than 64 ARFCNs, neither via the
config file, nor interactively from the VTY.
