GLib historically has been designed to be "mostly" portable; there are some functions only available on Unix like g_io_channel_unix_new(), but these are typically paired with obvious counterparts for Win32. However, as GLib is used not only by portable software, but components targeting Unix (or even just Linux), there are a few cases where it would be very convenient if GLib shipped built-in functionality. This initial patch is a basic wrapper around pipe2(), including fallbacks for older kernels. This pairs well with the existing g_spawn_*() API and its child_setup functionality. However, in the future, I want to add a signal() wrapper here, complete with proxying the signal to a mainloop. I have initial code for this, but doing it sanely (including factoring out gmain.c's private worker thread), is a complex task, and I don't want to block on that. See also gwin32.h for Win32 specific functionality. https://bugzilla.gnome.org/show_bug.cgi?id=644941
