SMPP: Add new 'dcs_transparent' ESME setting
If an ESME has the dcs_transparent config flag, then the TP-DCS
of MO-SMS is transparently passed to SMPP and not converted to SMPP
specific data_coding values.
This is needed in cases where ESMEs actually care about the exact
TP-DCS, as the conversion from TP-DCS to SMPP data_coding is not
bijective.
