Change subject: VLR: send CHECK-IMEI to EIR/HLR
......................................................................
VLR: send CHECK-IMEI to EIR/HLR
When check-imei-req is enabled in the VTY config, do not accept IMEIs
sent by the ME directly anymore. Send the IMEI to the EIR/HLR and wait
for its ACK or NACK.
OsmoHLR also accepts all IMEIs at this point, but this allows to
optionally store the IMEI in the HLR DB.
