[platform-debug-dev] IBreakpoint listener API

[Jared Burns <jared-eclipse@xxxxxxxxx>]

The breakpointChanged(...) and breakpointRemoved(...) methods both take a 
breakpoint and an IMarkerDelta. If possible, I'd like the API to be changed 
to allow the marker delta parameter to be null.

This is useful in the case where a breakpoint property is set that is not 
stored on the marker. The specific case I have is the breakpoint thread 
filter. When a thread filter is added, breakpoint listeners (like the 
breakpoints view) should be informed of the change, but the change does not 
generate a marker delta.

Any thoughts?
