The TITAN TTCN-3 compiler from Eclipse is not happy about the
naming of the ASN.1 modules. Let's rename as recommended.
ttcn3_makefilegen: error: The file name `LibS1AP/asn1/S1AP_PDU-Contents.asn'
(without suffix) shall be identical to the module
name `S1AP-PDU-Contents'. If the name of the ASN.1
module contains a hyphen, the corresponding file
name shall contain an underscore character instead.
