hivex: Modify children/values functions to return intermediate blocks.

Modify the functions that return child subnodes and values so they
can also be used to return a list of the intermediate blocks.  This
is so we can delete those intermediate blocks (in a later commit).

We also introduce an offset_list structure which is used for collecting
lists of offsets, ie. lists of nodes, values or blocks.

Note that this commit should not change the semantics of the code.

14 years agohivex: Add value_any callback to the visitor.

hivex: Add value_any callback to the visitor.

The visitor currently contains lots of value_* callbacks, such as
value_string which is called back when the value has type string.

This is fine but it makes it complicated to deal with the case where
you just want to see 'a value', and don't care about its type.

The value_any callback allows visitors to see values generically.
