Make it possible to trigger a debug-attach in a running instance
of Qt Creator by means of -client, use that in qtcdebugger, thus
enabling it to attaching to crashing executables in run mode
(Windows/CDB).

Modify IPlugin and application so that the complete command line is
serialized and transmitted to a running instance via QtSingleApplication
if -client is specified. Introduce IPlugin::remoteArgument and use that
in core for opening files and in the debugger for attaching.

Use -client in qtcdebugger with some logic to keep it alive as long as
the debuggee, make CDB break in that case as the events are not replayed
correctly in case the debugger is not spawned by the registered handler.

For device debugging. Move both from namespace
Debugger::Internal to Debugger, export them, give
DebuggerManager a static instance().

and ApplicationRunConfiguration to LocalApplicationRunConfiguration,
preparing remote debugging. Change the interface canRun() to be const,
run() to create() (since it does not run anything), use references
to the QSharedPointer<Foo>. Introduce d-Pointer and remove
unneeded headers from ProjectExplorerPlugin and add missing includes
everywhere.

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

"Stepping instruction wise" and "display disassembler" mode is now toggled by a
single action. This also allows to re-use F10 and F11 as keyboard shortcut.

Missing: caching of disassembler output, removal of old disassembler view.

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.

Introduced struct DebuggerStartParameters to pass around
start parameters, removing the need for the engines to
access private members of DebuggerManager. Pass it
to DebuggerManager::startNewDebugger() and move
the GUI parts of that function into DebuggerPlugin,
making it possible to create the struct from command line
parameters. Introduce command line parsing with a few more
-enable-xx options. Introduce warning() to debugger panel
in the CDB engine.

On this occasion, clean out a few trailing whitespaces.

Modify engine creation funcs to populate a list of option pages
to be able to handle engine enabling independently of the
actual engine creation.
