Annotation improvements:

Now the default annotate browser uses a much more compact format, implementing
suggestions made made by several people, notably Linus.

Here is part of the new __list_del_entry() annotation:

The infrastructure is there to provide formatters for any instruction,
like the one I'll do for call functions to elide the address.

Further fixes on top of the first iteration:

- Sometimes a jump points to an offset with no instructions, make the
  mark jump targets function handle that, for now just ignoring such
  jump targets, more investigation is needed to figure out how to cope
  with that.

- Handle jump targets that are outside the function, for now just don't
  try to draw the connector arrow, right thing seems to be to mark this
  jump with a -> (right arrow) and handle it like a callq.
