Since Wireshark includes glib, you can take advantage of glib's hash table
API to store your ID/string mapping in a hash table.  If the table is global
to your dissector code, then each time your dissector is run it will have
access to the whole table and can look up the strings as needed.

To make the hash table global to your dissector, simply declare it at the
top of your dissector source file, below the #includes but above the C
functions. Make sure you create the hash table in your init code, and add
the 'insert' and 'lookup' calls in your dissect function(s).

The Glib hash table API is described here:
