Format pointers consistently using 0x%[l]x in printf/scanf.
Remove %p formatting as the existence of the prefix 0x
is platform-dependent (missing with MSVC), which caused
a scanf error and thus dumper crash for QAbstractItem.

Handle QVariantList within dumpers, as gdb does not resolve
typedefs. Disconnect the gdb process on exit, one more round
of event loop when quitting.

_HAS_ITERATOR_DEBUGGING asserts can cause the debugger to be in an
inconsistent state and should thus be avoided. Add checks on the
underlying red/black tree structures using friend helper classes.

Clear a failed call. _HAS_ITERATOR_DEBUGGING can unfortunately
not be turned off as it is not binary compatible with other code.

- If NSX and NSY have quotes for the QT_NAMESPACE case, they need them
  for the non-namespace case too.
- Dumper autotest: Replace hard-coded namespace with compile-time
  dynamic one.

CDB can now handle sizeof(Class) and even expressions that
determine the offset of map node values (to some extent), may still
fail with templates). Format expressions accordingly, adapt
cached expressions.
Use gdbQuoteType depending on debugger type only.
Most important, do not evaluate each expression separately before
issuing the call, as ".call" can now do it on its own. Check for syntax
errors there and cache failing types as before.

- Do not deref d-ptr when checking on QVariants of PODS
- Make type/value fixing of dumper results more fine-grained
- Allow children in expandPtrToDumpage (QWidget-Pointers)
- Fix broken size cache (queuePrefix was empty)
- Compile

..preparing recursive dumpers. Add recursive parser to
watchutils.cpp Use insertBulkData() within CDB, add sizeof()
information for some Qt containers in order to be able to
dump QList<QList<KnownType> > .

Change dumper protocol 1 output not to contain type names as
hash keys (might contain blanks), use lists instead.
Start fixing autotests for 4.6.

Split the concepts 'enabled' and 'editable' in the dumper output
Disable "<not in scope>" entries, also fix their type.
Fix glitch in type beautification for display
Find reason for failing bulk updates.

Add a dumper for QStack. Also don't crash when accessing an uninitialized
pointer when the pointer looks bad to begin with.
