Jacob Erlbeck 93c55d04e5 rlc: Add and use mod_sns(bsn) method
Currently there is only a mod_sns() method which is being used in
expression like bsn_expr & win.mod_sns(). This only works, because
it is known that mod_sns() is (sns() - 1) where sns() in turn is
always 2^n. This is error prone, hard to read, and relies on window
specifics that should be kept inside the respective module.

This commit adds a mod_sns(uint bsn) method to gprs_rlc_ul_window and
gprs_rlc_dl_window, that encapsulates and hides this optimized
computation.

README

This is an implementation of Packet Control Unit (PCU) according to TS 04.60

The PCU is part of BSS, so it connects directly to SGSN.


== Current limitations ==

 * No PFC support
 * No fixed allocation support
 * No extended dynamic allocation support
 * No unacknowledged mode operation
 * No PCCCH/PBCCH support
 * Only single slot assignment on uplink direction
 * No half-duplex class support (only semi-duplex)
 * No handover support
 * No measurement support
 * No TA loop
 * No power loop
 * No CS loop
 * No EGPRS
