alloc: Replace Algorithm B implementation

The current implementation always starts the downlink slot allocation
with the first possible slot, depending on which channels are enabled
and which multislot class is offered by the MS. So in configurations
with many (>4) PDCH, some PDCH are not really used.

The new implementation introduced by this commit differs as follows:

 - The reservation mechanism provided by GprsMs is used to avoid
   incompatibilities is used in the same way like algo A does. This
   basically means, that the allocation is done once when the first
   TBF is requested and then used until all TBF have been released.

 - All combinations of Rx and Tx slots are checked for compatibility
   with the multiscot class. Basically the combination with the most
   usable PDCH and the least number of reservations is used.

 - Only one UL slots is provided.

 - Tta and Tra are checked.
