Correct Zero/Null as pointer constant ( #1938 )
...
Building with enhanced clang warnings indicated a large number of
instances with the warning:
`warning: zero as null pointer constant`
Recommended practice in C++11 is to use `nullptr` as value for
a NULL or empty pointer value. All instances where this warning
was encountered were corrected in this commit.
Where warning was encountered in dependency code (i.e. external library)
no chnages were made. Patching will be offered upstream.

There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..

Fix crash bug #8579 ( #1238 )
...
* Added declaration for deletePrevious function
* Added definition for deletePrevious function
* Fixed crash from deleteThis invalidating pointers
The crash was caused by deleteThis() invalidating the pointer to a constant variable usage. This happened when a usage followed an assignment. This fixes bug #8579 .
* Added tokensFront to match tokensBack
This means deletePrevious can set the list's front if necessary.
* Initialised tokensFront in appropriate places
* Switched to using default Token constructor
* Switched to using Token default constructor
* Switched to using default constructor for Token
* Added missing argument to Token constructor
* Changed to use default constructor for Tokens
* Switched to using default constructor for Tokens
* Switched to using default constructor for Token
* Added new test for deleting front Token
Also made sure to use the correct constructor for Token in other tests.
* Syntax error
* Replaced tokensFront and tokensBack with a struct
This decreases the size of the Token class for performance purposes.
* Replaced tokensFront and tokensBack with a struct
* Added tokensFrontBack to destructor
* Reworked to use TokensBackFront struct
Also ran astyle.
* Reworked to use TokenList's TokensFrontBack member
* Reworked to use TokensFrontBack struct
* Reworked to use TokensFrontBack struct
* Reworked to work with TokensFrontBack struct
* Removed unnecessary scope operator
* Added missing parentheses
* Fixed syntax error
* Removed unnecessary constructor
* Default constructor now 0-initialises everything
This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.
* Fixed unsafe null check
* Added missing explicit keyword
* Fixing stylistic nits
Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.
* Fixing stylistic nits
Removed default constructor and replaced it with a single-argument constructor with a default value.
* Fixing stylistic nits
Renamed _listEnds to _tokensFrontBack.
* Fixing stylistic nits
Renamed _listEnds to _tokensFrontBack.
