If no exception handling is provided when calling a managed delegate from native
code, and the managed code throws, then we'll abort.
It's not entirely clear how we'll handle managed exceptions that go through native
code yet, so this makes the initial implementation easier. By making the exception
handling optional, it'll be easy to find all cases where we need to fix it later,
by making it non-optional. The alternative is to add exception handling code all
over the place that would potentially have to be updated when we figure out exactly
what needs to be done.
Mark managed callback functions if they're only used in the dynamic registrar,
and only initialize the corresponding delegate if the dynamic registrar is
available.
This will make it possible for the linker to remove those managed functions if
the dynamic registrar is being removed.
We already have the information we need to generate these function
declaration, so this prevents the need for keeping information in two
different places up-to-date.
