* Make the TBF ul/dl list per BTS * Make the SBA per BTS * Make the tbf point to the BTS so we can kill plenty of parameters * Group more into in classes.. remove bts pointers. * Change functions with 100 parameters to get a struct as param * Move move into the TBF class * Replace trx/ts with pointers. E.g. a PDCH should know the trx it is on... then we can omit trx, ts and parameters and just pass the pdch. * On global free/reset... also flush the timing advance.. * tbf/llc window code appears to be duplicated and nested in other methods. This needs to be cleaned.
