Pete Johns 502cfe7243 Fixed #2384 ("The function 's::f' can be const" reported for pointer-to-pointer)
Moved check for pointer variables into isVariableDeclaration()

Can now handle multiple scopes and multiple levels of indirection. Simplified check for strucs and unions, too, reducing the size of getVarList().

skipScopeIdentifiers() and skipPointers() should probably be methods on class Token.

Extracted method isVariableDeclaration()

Added unit tests for isVariableDeclaration in new file testsymboldatabase.cpp

Extracted givenACodeSampleToTokenize helper class into testutils.h to reduce duplication.
