[Vala] g-unix-*.-stream bindings

[Mikael Hermansson <mike tielie gmail com>]

I tried to create bindings for g_unix_*-stream API but I dont know if
its correct.

vapigen didnt get any warnings atleast.

But when i try too compile an example app valac --pkg gio-unix-2.0
test.vala

didnt compile it cant find the package...


Would be great if some maintauner could fix it and upload it to svn :-)
