[PULL wayland] More OS compatibility wrappers

[Pekka Paalanen]

Hi Kristian,

here are the rest of my OS compatibility wrappers for Wayland. Every
wrapper, except accept4, has two unit tests: a normal one and a forced
fallback one.

The accept4 patch adds a configure test for it, the others seemed to
work by preprocessor directives.

There are also some wrapper and test cleanups, and the last patch fixes
a theoretical bug (I believe).

Thanks to Thiago Macieira for feedback on the wrappers, and also to
vapula on #wayland.
