[Mono-osx] Invoke CIL/Managed Code from ObjC/XCode on Mac

Yes using the pkg-config is the correct way to find the settings.  Which is
exactly what I did.  However, with Xcode you cannot execute scripts in the
build settings.

I gave enough details on how to easily embed a DLL within ObjC.  Change the
reference in main.m from MacMonoClient.exe to MacMonoClient.dll.  Change the
mono_jit_exec to something like this:

MonoClass *klass = mono_class_from_name (mono_assembly_get_image
(monoAssembly), "MacClient", "SetMeUp");
MonoObject *newObject = mono_object_new(domain, klass);
    if(newObject != NULL) {
        mono_runtime_object_init (newObject);

Of course have a CSharp class SetMeUp.  This by the way is what I did in
1.9, which no longer works in 2.0.  The SetMeUp constructor invoked the
Monobjc initilization methods.

Then try to invoke an internet request:

                HttpWebRequest httpReq = CreateHttpRequest(uri, false);

Please do update me on how calling the embedded DLL sets up the
configuration information.

Thanks for your help.
