Remove memory debugging/tracing support and all related options

Browse source 
Drop disabled by default and pretty useless memory tracing code and all
the overlapping and poorly documented build options related to it.

Remove memory.cpp entirely and update all the make/project files, but
preserve the now completely trivial wx/memory.h for compatibility and
also keep including wx/string.h from wx/object.h as it seems like a lot
of existing code actually depends on this, even if it should not.

Replace the options in the propgrid sample with a couple of other
debug-related options that were not used before to avoid leaving the
"Debugging Section" completely empty.

// is no overhead if you don't use it
#define wxUSE_DEBUGREPORT 1
// Generic comment about debugging settings: they are very useful if you don't
// use any other memory leak detection tools such as Purify/BoundsChecker, but
// are probably redundant otherwise. Also, Visual C++ CRT has the same features
// as wxWidgets memory debugging subsystem built in since version 5.0 and you
// may prefer to use it instead of built in memory debugging code because it is
// faster and more fool proof.
//
// Using VC++ CRT memory debugging is enabled by default in debug build (_DEBUG
// is defined) if wxUSE_GLOBAL_MEMORY_OPERATORS is *not* enabled (i.e. is 0)
// and if __NO_VC_CRTDBG__ is not defined.
// The rest of the options in this section are obsolete and not supported,
// enable them at your own risk.
// If 1, enables wxDebugContext, for writing error messages to file, etc. If
// __WXDEBUG__ is not defined, will still use the normal memory operators.
//
// Default is 0
//
// Recommended setting: 0
#define wxUSE_DEBUG_CONTEXT 0
// If 1, enables debugging versions of wxObject::new and wxObject::delete *IF*
// __WXDEBUG__ is also defined.
//
// WARNING: this code may not work with all architectures, especially if
// alignment is an issue. This switch is currently ignored for mingw / cygwin
//
// Default is 0
//
// Recommended setting: 1 if you are not using a memory debugging tool, else 0
#define wxUSE_MEMORY_TRACING 0
// In debug mode, cause new and delete to be redefined globally.
// If this causes problems (e.g. link errors which is a common problem
// especially if you use another library which also redefines the global new
// and delete), set this to 0.
// This switch is currently ignored for mingw / cygwin
//
// Default is 0
//
// Recommended setting: 0
#define wxUSE_GLOBAL_MEMORY_OPERATORS 0
// In debug mode, causes new to be defined to be WXDEBUG_NEW (see object.h). If
// this causes problems (e.g. link errors), set this to 0. You may need to set
// this to 0 if using templates (at least for VC++). This switch is currently
// ignored for MinGW/Cygwin.
