It seems that `typestr` does not always define the final size of the element. And it varies by operating system.
Then use the `typestr` only to know the itemtype is `float` type or not.
This was meant to be generic but introduced possible type errors
and unnecessary complication.
Replace with typed PyC_Tuple_PackArray_* functions.
Also add PyC_Tuple_Pack_* macro which replaces some uses of
Py_BuildValue, with the advantage of not having to parse a string.
Python's C-API doesn't provide functions to get
int's at specific integer sizes.
Leaving the caller to check for overflow,
which ended up being ignored in practice.
Add API functions that convert int/uint 8/16/32/64, also bool.
Raising overflow exception for unsupported ranges.
The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

These are from the ARB_vertex_type_2_10_10_10_rev extension that became part of OpenGL 3.3.
So they are new, but only exist for compatibility with immediate mode, which is old.
