cppcheck-1.82-bp151.2.16

- Update to version 1.82
  Bug fixes:
  * Better handling of namespaces
  * Fixed false positives
  * Fixed parsing of compile databases
  * Fixed parsing of visual studio projects
  Enhancements
  * New check; Detect mistakes when there are multiple strcmp() in
    condition
    Example:
    if (strcmp(password,"A")==0 || strcmp(password,"B")==0 || strcmp(password,"C"))
    There is a missing '==0', and therefore this condition is
    always true except when password is "C".
  * New check; pointer calculation result can't be NULL unless
    there is overflow
  Example:
    someType **list_p = ...;
    if ((list_p + 1) == NULL)
  The result for '(list_p + 1)' can't be NULL unless there is
  overflow (UB).
  * New check; public interface of classes should be safe - detect
    possible division by zero
    Example:
    class Fred {
    public:
    void setValue(int mul, int div) {
    value = mul / div; // <- unsafe
    }
    ...
    This check does not consider how Fred::setValue() is really
    called.
    If you agree that the public interface of classes should
    always be safe; it should be allowed to call all public
    methods with arbitrary arguments, then this checker will be
    useful.
  * Fixed a few false negatives
  * More information in the cfg files
  version 1.81
  CPPCHECK:
  * New warning: Check if condition after an early return is
    overlapping and therefore always false.

    during build)
