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.
Related to T49165 (general OpenGL upgrade)
- Adds support for word wrapping to Blender's BLF font library.
- Splits lines when width limit is reached or on explicit \n newlines.
Details:
- Word wrapping is used when `BLF_WORD_WRAP` flag is enabled.
- There is a single loop to handle line wrapping,
this runs callback, passing in a substring,
this way we can avoid code-duplication for all word-wrapped
versions of functions... OR... avoid having to add support
for word-wrapping directly into each function.
- The `ResultBLF` struct was added to be able to get the number
of wrapped lines, when calling otherwise unrelated functions
such as `BLF_draw/BLF_width/BLF_boundbox`,
which can be passed as the last argument to `BLF_*_ex()` functions.
- The `ResultBLF` struct is used to store the result of drawing
(currently only the number of lines wrapped, and the width).
