of an empty handle in case of an exception.  This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.

The issue is that exceptions are not rescheduled if they are
externally caught.  Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

Whenever a script object is created it is assigned a unique id. Currently this id is assigned from an 32 bit integer counter.

Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.

This has the side effect that function break points are not converted into script break points for named scripts.

Show the script id in the D8 shell debugger when listing all scripts using the 'scripts' command.

Sharing the code to unlink the exception handler for a try/finally
causes us to try to merge virtual frames with different heights (due
to statements that keep state on the stack) at the entry to the unlink
code.

Avoid this by unlinking the handler separately for each exit from the
try block.

Change the tests which looks at the number of scripts in the VM after startup to ignore native scripts without name.

Native scripts without name are currently only the script holding the empty script and the script holding the source for the empty function. These two unnamed scripts are created for each context.
