From 5a7a80e139396c07d45e70d63c6d3974c50ae5e8 Mon Sep 17 00:00:00 2001

Subject: GDSDB: Make sure our offset advances.
add_uint_string() returns the next offset to use, not the number
of bytes consumed. So to consume all the bytes and make sure the
offset advances, return the entire reported tvb length, not the
number of bytes remaining.
