 * mono_add_internal_call:

 * that has been surfaced in managed code with the method specified in
 * \p name as an internal call.
 *
 * Internal calls are surfaced to all app domains loaded and they are
 * accessibly by a type with the specified name.
 *
 * You must provide a fully qualified type name, that is namespaces
 * and type name, followed by a colon and the method name, with an
 * optional signature to bind.
 *
 * For example, the following are all valid declarations:
 *
 * \c MyApp.Services.ScriptService:Accelerate
 *
 * \c MyApp.Services.ScriptService:Slowdown(int,bool)
 *
 * You use method parameters in cases where there might be more than
 * one surface method to managed code.  That way you can register different
 * internal calls for different method overloads.
 *
 * The internal calls are invoked with no marshalling.   This means that .NET
 * types like \c System.String are exposed as \c MonoString* parameters.   This is
 * different than the way that strings are surfaced in P/Invoke.
 *
 * For more information on how the parameters are marshalled, see the
