ogc-sys: no bindings generated for static inline methods

[TomSmeets]

In the process of trying to convert the triangle example from https://github.com/devkitPro/wii-examples/blob/master/graphics/gx/triangle/source/triangle.c to rust I noticed that multiple methods including GX_End() where missing from ogc-sys.
All these methods are static inline methods in libogc/include/ogc/gx.h

These methods should somehow be directly converted to rust because they are not exported.
Note that GX_End() doesn't actually do anything at all. And the other methods are very simple.

A relevant issue in rust-bindgen is rust-lang/rust-bindgen#1090

All inline methods in gx.h

Interesting, will have to go through and see if any other functions were affected by this issue.

Implementing the mentioned functions in libogc/include/ogc/gx.h seems simple enough. Those functions should probably be made unsafe or have safety documentation instructing the user of what happens.

[FrictionlessPortals]

These functions have been implemented into ogc-sys as of PR #8.

Feel free to reopen this issue if any error occurs when using the implemented functions.
