012ec01 by Guy Harris (guy@xxxxxxxxxxxx):
Add additional checks, clean up some stuff.
Add checks for bad block lengths - either too short or not a multiple of
4. (Yes, the pcapng spec requires it to be a multiple of 4. And there
is at least one implementation that requires it.)
For various structures with a length field, create the top-level tree
field for the item with a "run to the end of the packet" length and,
once we're finished dissecting it, set the length to its actual value.
Fetch various field values using proto_tree_item_add_uint. Fix some
incorrect field types based on errors reported by that.
If an end-of-options option has a non-zero length, 1) don't treat it as
not an end-of-options option and 2) report an error on its length.
