Rolf Bjarne Kvinge a4dffa6a78 [runtime] Disable the GC pump for Xamarin.Mac. (#52) 
It seems it prevents the app from exiting; Mono will wait
for the GC pump thread to exit, which never happens.

The GC pump was never enabled for Xamarin.Mac apps
until recently (d9677714a), so this will just revert
to the previous behavior.

Native runtime

This directory contains the native runtime for Xamarin.iOS and Xamarin.Mac.

Generated code

A few files are generated automatically:

delegates.h|inc, Delegates.cs

These files contain the code required to glue the native runtime and the managed runtime.

mono-runtime.m, xamarin/mono-runtime.h

These files contain code that makes other code, consumers of the mono runtime, oblivious to whether the mono runtime is linked statically, dynamically, or using dlopen at runtime.

If you need to use a new function from the Mono headers, add it to exports.t4.

If you need a new enum / constant / typedef / etc, add it to mono-runtime.h.t4.

Shipped headers

These are the headers shipped with XI/XM (they're not for public consumption, but we need them to build generated code on customers machine, in particular main.m and registrar.m)
