Something's visible in Locals&Watchers now!

That's the first step to make the gdb/trk Adapter work with the otherwise
unmodified gdb engine. GdbProcessBase is inherited by GdbProcess and the
gdb/trk Adapter. In the GdbProcess case it's just a wrapper around a QProcess
running gdb, in the Adapter case it's the interface to the gdb process in the
whole rfomm/gdb/gdbserver combo.

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.

There was a case where "childtype" had to be used instead of "type".

the child list.

It was merged to Qt master a while ago.

when stopping debugging.

It is replaced by a real editor in e82d6c7b.

"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.

Show the current number base in the view.

Just mentioning it in the status bar is often not enough to take notice.

When trying to debug qmake or another bootstrapped application loading the
dumpers failed as they are binarily incompatible. So failing is expected and
fine. However, gdb 6.8-debian produces in this case _two_ responses for
'-exec-continue produces' ('^running' and '^error,msg="Cannot find new threads:
generic error"') which is impossible according to the MI docs. In theory...

Fix "displayedtype" in CDB, display it elsewhere.

Requires a lot of trivial forwarding.

There were both variants, with and without extra semicolon.

There used to be a single 'Locals' etc item of the true root that was
never shown anyway. Removing this also renders using setRootIndex()
in WatchWindow unnecessary.

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.
