Add support for parsing C++11 =delete and =default

Browse source 
Although this was documented as working, it wasn't implemented
%typemap(default) failed without the idstring changes
Add some C tests using the C++ keyword delete

<p>SWIG correctly parses the <tt>= delete</tt> and <tt>= default</tt>
keywords. For example:</p>
<p>SWIG handles explicitly defaulted functions, that is, <tt>= default</tt> added to a function declaration. Deleted definitions, which are also called deleted functions, have <tt>= delete</tt> added to the function declaration.
For example:</p>
<div class="code"><pre>
struct NonCopyable {
NonCopyable&amp; operator=(const NonCopyable&amp;) = delete; /* Removes operator= */
NonCopyable(const NonCopyable&amp;) = delete; /* Removed copy constructor */
NonCopyable() = default; /* Explicitly allows the empty constructor */
void *operator new(std::size_t) = delete; /* Removes new NonCopyable */
NonCopyable(const NonCopyable&amp;) = delete; /* Removed copy constructor */
NonCopyable() = default; /* Explicitly allows the empty constructor */
void *operator new(std::size_t) = delete; /* Removes new NonCopyable */
};
</pre></div>
<p>This feature is specific to C++ only. The defaulting/deleting is currently ignored, because SWIG
automatically produces wrappers for special constructors and operators specific to the target language.</p>
<p>
Wrappers for deleted functions will not be available in the target language.
Wrappers for defaulted functions will of course be available in the target language.
Explicitly defaulted functions have no direct effect for SWIG wrapping as the declaration is handled
much like any other method declaration parsed by SWIG.
