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.

This commit removes the code that is no longer used due to the commit
"Use a single PDCH rcv_data_block method for GPRS and EGPRS".

The current rcv_data_block_acknowledged_gprs method is tightly
coupled to GPRS.
This commit adds variants of the involved methods that support
EGPRS and GPRS RLC encodings likewise.

Currently gprs_rlc_ul_window::receive_bsn calls raise_v_q and returns
the number of RLC data blocks that can be taken from the queue. This
does not fit the EGPRS feature to put 2 independant data blocks in a
single RLC block.
This commit removes raise_v_q from receive_bsn, hence it must be
called explicitely to get the number of processable data blocks.

This commit renames rcv_data_block_acknowledged to
rcv_data_block_acknowledged_gprs to separate it from EGPRS data block
decoding.

This commits adds the GprsMs::update_l1_meas() and GprsMs::l1_meas()
methods to store and access the measurement values. The internal
state is updated depending on which values are actually set.
In addition, these values are shown in the output of the 'show ms
imsi|tlli' command.

Currently only the RSSI value is passed to the upper layers. Other
values like TA and BER which are needed for TA update respectively CS
selection are not propagated.
This commit introduces and passes a struct that contains a set of
measurement values.
