Fix hidden overloaded methods

GoogleCodeExporter commented 8 years ago

Compiling an application using bullet with clang results in 
-Woverloaded-virtual warning messages in btConvexHullShape.h:

In file included from lib/ephysics/ephysics_constraints.cpp:5:

note: hidden overloaded
      virtual function 'btConvexShape::project' declared here
        virtual void project(const btTransform& trans, const btVector3& dir, btScalar& min,...

The reason is that the compiler stops searching for methods in the parent class 
if it find any method with the same name defined in the child, as explained in:

http://stackoverflow.com/questions/585913/c-member-function-virtual-override-and
-overload-at-the-same-time

Importing the parent declarations solves the problem. Example patch is attached.

bullet 2.81, Arch Linux amd64
