more verbose than base64 but also less work on the dumper side

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.

Add a configuration checking method to the Debugger manager,
depending on toolchain, wire it to the engines.
Check that in the debugger run controls.

Add a convenience method to ICore that shows a warning
message with a "Settings" button, pointing the user
to a configuration error on a settings page.

Remove leftovers of the dumper parser.

This might lead to false positives in corner cases like empty structures
but speed up the display of arrays and lists of user-defined types a lot.

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.

Was broken due to a change in the QVector implementation (See 343e848abc1 and
a07385de156 in Qt master)

- std::set/map: Introduce templates to iterate the MSVC STL
  implementation depending on type (since it inherits some
  basic set_traits that depend on the key/value size.
- Retrieve types correctly in CDB (buffer too short for STL-types)
- Fix std::map in GDB broken by previous commit.
- Introduce a dumper version check in GDB/CDB.
- Make GDB parse sizes in initial dumper call as well
- Fix special sizes to work with namespaced Qt (watchutils)

- Make container dumper routines set "childnumchild" when known
  in order to avoid roundtrips; avoid repeated invocations of
  container.end().
- Completed dumper information in some places to avoid roundtrips.
- Extended QVariant helpers by dumpers for common GUI types
  (rectangles, points, sizes, fonts, size policies).
- Introduced artificial QObjectChildList/QObjectProperty types to
  be able to dump QObject children and properties without using
  gdb expressions.
- Fixed dumping of Signal/Slot list to pass on correct types. Avoid
  recursions if signal is connected to self.
- Replaced expressions by addresses in the dumpers to it make work
  for CDB.
- Reworked dumper test program to have -a, making it usable for tests,
  add further types.
- Gdb: Clear output buffer before calling dumpers, avoiding mixups
  in case evaluation of expression fails.
- Fix the dumper parser used by CDB, do not be fooled by
  "<synthetic>" addresses, etc.
- Pass on a "dumperVersion" in initial query.

- Fix extractTemplate() not to kill blanks in case there is no
  blank after a comma, fix hardcoded types accordingly.
- Make niceType()'s regexps ignore blanks after commas, add
  unsigned short as char_type and cache the mappings, making
  them work for CDB.
- CDB: Parse map output of dumpers correctly, generally don't
  confuse the parser by unknown keywords encountered when
  parsing children, thus enabling simple QMap types.
- Make dumpInnerValueHelper output std::string types.

Make dumpers pass on more size information initially, namely the
various Q<>Pointers. Introduce enum for those special template types
whose size does not vary with the arguments (Q<>Pointer,
std::allocators...) to make it more easily extensible.
Pass on some common QMapNode<> sizes as well.
Introduce an expression cache to the common QtDumperHelper
class and make dumpers pass some common expression values
(value offsets of common QMapNode<> incarnations).
Make CDBDumperHelper use the expression cache.
Extend dumper tester.

prevent inter-session dependencies

This also squashes a namespace related bug introduced by the watchutils
refactoring.

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.
