John Thacker 4f3b028d94 epan: Separate fragment_head and fragment_item 
Separate fragment_head and fragment_item into two
different types of structs.

Remove "offset" from fragment_head, which was unused,
making fragment heads 4 bytes smaller.

Remove fragment_nr_offset, datalen, reassembled_in,
reas_in_layer_num, and error from fragment_item,
making them 24 bytes smaller.

Change a few dissectors which were using fragment_head
and fragment_item indistinguishably.

Hannes Mezger 28a7a79cac opcua: prevent opcua dissector crash by limiting nesting depth 
The OPC UA types DiagnosticInfo, Variant and ExtensionObject can be
nested, which can lead to stack overflows when parsing specially
crafted packets. This is fixed by storing the current nesting depth
as expert info.
The corresponding CVE is https://cve.mitre.org/cgi-bin/cvename.cgi?name=2018-12086
The corresponding security bulletin of the OPC Foundation is https://opcfoundation-onlineapplications.org/faq/SecurityBulletins/OPC_Foundation_Security_Bulletin_CVE-2018-12086.pdf
