Added convenience method for checking if two numbers
are not equal

Added #include <cassert> for the definition of assert()

Introduce AMR-Kit in to the build and two additional
classes: (a) vtkSerializable and (b) vtkAssertUtils.
The AMR-Kit is geared towards encapsulating all of
the AMR infrastructure & algorithms. vktSerializable
defines a pure abstract interface for all serializable
objects. Last, the vtkAssertUtils is a singleton class
provides functionality for self-checking that is enabled
only when -DASSERT_ON is provided.

The sqrt was in error, since the normalization coefficient is
being applied to the matrix elements, not to the original
quaternion elements.  Thanks to Tamas Ungi for pointing this out.

This reverts commit befcaa27. This
change turned out to be a terrible idea due to operator overloading
confusion, and in retrospect the presence of this implicit cast is quite
undesirable. Several parts of the code rely on it being inaccessible
when working with a const ref of a vtkStdString on some platforms. You
should use the real, explict c_str() method which is marked const.

Prevent issue with multiple available overloads not that const char*
operator is const in vtkStdString.

The i386 code only helped on old, non-SSE CPUs or on
old compilers that didn't use SSE instructions.

Change so that if the special character was already getting
escaped that I still escape the ampersand. For example,
'<' in the attribute value or character data would
be changed to '<'.

In vtkOpenGLScalarsToColorsPainter::GetTextureSizeLimit()
I now initialize textureSize before calling openGL.
Also the Tcl test for getting the result of this function
is turned off.

Attribute value strings and character data that had the XML
", ', &, <, and > special characters are replaced with &quot;,
&apos;, &amp;, &lt;, and &gt;, repectively, during printing.

The internal wrappers simply skip these methods when the
method signature includes a reference to the typedef rather
than the raw function pointer type.

Leave the typedef in, for external analysis tools that can
infer a match between the typedef and the use of the
corresponding raw function pointer type.

But eliminate its use from the signatures of the methods
so that the internal wrapping tools still wrap these methods.

Especially important, as these methods are explicitly designed
to be used from the wrapped languages.

Add ProgrammableMethodCallbackType typedefs to all the programmable object
classes so the wrapping tool for ActiViz can automatically generate delegate
types in the C# classes with no manual intervention. The presence and usage
of a named typedef for any function pointer type referenced from a wrapped
method gives the wrapping tool all it needs to generate delegate types
automatically.

Also, use __stdcall on Windows builds so that the C++ calling convention
matches the default one used for the generated delegates. You can override
this choice by providing a definition of VTK_CB_CC using -D on the compiler
command line if you want a different calling convention for these callbacks.

Functionality is unchanged except for the calling convention change.
The code now simply uses the named typedef rather than an anonymous type as
a parameter in each SetExecuteMethod signature. Also used in the other
programmable methods with the same signature.

There was a number of colors limit (256 in v3.8, and currently 1024)
set in vtkScalarsToColorsPainter which is now changed to be
limited by the nubmer of opengl texture colors.  The changes to the
other files are for specifying the amount of available colors
in those lookup tables.
