From Pascal Quantin:

Currently Wireshark limits the Access Point Name length to 50 bytes. But
according to 3GPP 24.008 chapter 10.5.6.1, the maximum length is 100 bytes (102
bytes minus the IEI and length fields) and not 50.
The attached patch increases the MAX_APN_LENGTH define value and allow the
correct display of an APN with a size greater than 50 bytes.
