This mainly allows for more precise shutdown and tightens the set
of allowed transitions.

See Qt Merge-request: 727, change a9c8decc741d8c2b340f38d7a854ef206672ab3e,
which makes wchar_t a native type. QString::toUtf16() no longer is
a WCHAR.

Fits better into the scheme and makes grep^H^H^H^H Ctrl-F-ing easier.

This updates the state diagram in debuggerplugin.cpp and
renames AdapterStart{Fail}ed to EngineStart{Fail}ed.

CDB: Add more information and state to Thread.
Refactor thread information in CdbCore classes to prepare for more
information.

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).

...to fix multithread crash.
Fix exit crash by temporarily removing output.

Wrote down what hjk told me.

Pass output through the RunControl instead of the DebuggerManager.

Plan is to identify make identify an IDebuggerEngine incarnation with
a RunControl.

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.

And use it from CDB's module load/unload callbacks
instead of re-setting all modules. Some cleanup./Fixed
