This improvement avoids use of deallocated memory (crash) if using a
deregistered field in display filter, color filter, custom column and
other cases when the field is used as "interesting field".
This functionality is currently used in http, imf and ldap preferences.
Also removed unused proto_registrar_n() as this does not work correctly
after deregistering fields.

Handling security fixes in source package wireshark
Wireshark is a network protocol analyzer and it's ability to perform deep
packet inspection in live traffic may encourage users to use Wireshark/Tshark
as a part of an intrusion detection or traffic monitoring system.
In that case, please note that Wireshark/Tshark may contain remotely
triggerable bugs causing crashes or allowing code injection.
Bugs allowing code injection will be fixed in regular Debian Security
Advisories, but fixes for pure crash bugs may be delayed.
