A mostly mechanical change.

This replaces the (de facto) singleton engines and data handlers by classes
that are instantiated per run. The DebuggerRunControl will now create an
object of (a class derived from) DebuggerEngine that contains all the relevant
"dynamic" data.

DebuggerManager is no more. The "singleton" bits are merged into DebuggerPlugin,
whereas the data bits went to DebuggerEngine.

There is no formal notion of a "current" DebuggerEngine. However, as there's
only one DebuggerEngine at a time that has its data models connected to the
view, there's still some "de facto" notion of a "current" engine. Calling
SomeModel::setData(int role, QVariant data) with custom role is used as the
primary dispatch mechanism from the views to the "current" data models
(and the engine, as all data models know their engine).

This replaces most uses of DebuggerStartParameters by DebuggerRunControl
which is a simple RunControl with a DebuggerStartParameters member.

Plan is to move all global state to the run controls, and possibly
introduce specialized ones for core debugging etc.

There is no shortcut associated with these actions, the user has to
set them up by himself.

Use BreakpointData objects for communicaition instead of random
collection of some of their attributes.
