Match insensitive.

Do not modify any packet. For local display, I would show the callsign
as received. So a list of messages from KD7LXL may look like this:

KD7LXL: Hello!
kd7lxl: Hello, again!
KD7lxl: My shift key is acting up!

Obviously it is impossible to send lowercase src calls in AX25, so
outgoing messages from your igate would have to be dropped if they
were lowercase (again, I wouldn't modify these).
