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).

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.

Intergrate per-engine state tracking with the global running/stopped state.

It is replaced by a real editor in e82d6c7b.

This reverts commit abf5e3dd.

- Modified WatchModel to handle storage of an hierarchy
  of WatchItems.
- Factored out code for asynchronous population to
  AsyncWatchModel and added a mixin for convenient
  handling
- Added base class for synchronous models.
- Implement simple, synchronous models for CDB, greatly
  simplifying code and finally getting manual
  expansion right.

It's now properly using canFetchMore/fetchMore. cdb is not yet ported.

Handle  the 2nd parameter correctly as a event id
to be used for a handshake. Introduce a special mode
when attaching to crashed processes.
Code cleanup, pass StartParameters along to startDebugger.

Make debugger tooltip API more general, have the engines check the
correct file type, figure out the expression and context from the text
editor.

Put common functionality in watchutils.cpp. In the CDB engine, check
whether a tooltip expression is a known variable within the stack frame
context. If so, retrieve via symbol group or dumpers. Cache by function
and expression.
