Review request for KDevelop.


While working on the kdevelop/gdb-side of things, I noticed that it makes sense to add the breakpointAdded() method to the IBreakpointController interface.

The other changes are fairly minor.

Repository: kdevplatform


Overall, I want to move the code into a shape where BreakpointModel stores all information about breakpoints as presented to the user, and IBreakpointController is a genuine thin interface with no code (or only shim code) in kdevplatform.

The changes are necessarily binary incompatible, but AFAIU this is okay in current kdevplatform and kdevelop master. There are also minor source incompatible changes; I have already updated kdevelop master so that it is compatible with them.

The next step after this set of changes will be to change the gdb plugin in kdevelop so that it no longer uses what is now marked as the "old API". This will reduce the interactions between kdevelop and kdevplatform. Once those changes have landed and are stable, the old API in kdevplatform can then be purged.

Besides the usual reviewing feedback and feedback on the general direction of these changes, I am particularly interested in:

1. Are there other users of the debuggers/breakpoint API, and source/binary compatibility policies that I should be aware of?

2. I introduced the Column and ColumnFlags enum, where the latter is intended to replace various sets by more compact bit fields. Is there a nice type-safe Qt way of having such a pair of enums, where one is for bitfield corresponding to sets of the other?
