Change subject: Update MCS selection for retransmission
......................................................................

Update MCS selection for retransmission

In 3GPP TS 44.060 the selection of MCS for retransmissions is defined as
separate tables (8.1.1.1 and 8.1.1.2) depending on the value of
resegmentation bit (which is opposite to the way EGPRS_ARQ are defined
in the source code). Let's follow the same idea and explicitly check for
resegmentation bit value and use separate tables. This also makes it
easier to add proper support for special cases (MCS-6-9 and MCS-5-7) and
padding in future independently for different ARQ types. The code is
also moved to c to avoid unnecessary conversions to and from cpp class.
