[pcap-ng-format] The record length in the Name Resolution Block appears to be a record *value* length

[Guy Harris]

In section 3.6 "Name Resolution Block (optional)" of the pcap-NG spec, it says:

   0                   1                   2                   3

	Each Record Value is aligned to a 32-bit boundary. The corresponding Record Length reflects the actual length of the Record Value.

From "reflects the actual length of the Record Value", and from the end_of_recs record having a length 0f 0, that sounds as if the Record Length does *NOT* include the Record Type and Record Length fields.  The spec should perhaps say that a bit more explicitly, or perhaps rename that field to "Record Value Length".
