Fixed crash and 64-bit porting issues

1. "emugen" generates four *dec.cpp files containing code like this
   to decode offset to pointer in stream

   tmp = *(T *)(ptr + 8 + 4 + 4 + 4 + *(size_t *)(ptr +8 + 4 + 4));

   If *dec.cpp are compiled in 64-bit, size_t is 8-byte and dereferencing of
   it is likley to get wild offset for dereferencing of *(T *) to crash the
   code.  Solution is to define tsize_t for "target size_t" instead
   of using host size_t.

2. Cast pointer to "uintptr_t" instead of "unsigned int" for 2nd param of
   ShareGroup::getGlobalName(NamedObjectType, ObjectLocalName/*64bit*/).
3. Instance of EGLSurface, EGLContext and EGLImageKHR are used as 32-bit
   key for std::map< unsigned int, * > SurfacesHndlMap, ContextsHndlMap,
   and ImagesHndlMap, respectively.  Cast pointer to uintptr_t and assert
   upper 32-bit is zero before passing to map::find().
4. Instance of GLeglImageOES is used to eglAttachEGLImage() which expect
   "unsigned int".  Cast it to uintptr_t and assert upper 32-bit is zero.
5. The 5th param to GLEScontext::setPointer is GLvoid* but contains 32-bit
   offset to vbo if bufferName exists.  Cast it to uintptr_t and assert
   upper 32-bit is zero.
6. Use %zu instead of %d to print size_t
7. Cast pointer to (uintptr_t) in many other places
