For various applications, we need a gperl_callback_invoke variant that traps
exceptions.

Since we can't change GPerlCallback, I think it would make sense to add a new
function gperl_callback_invoke_trapped that would basically be a copy of
gperl_callback_invoke with exception handling added.  The exception handling
code can be copied from GPERL_CLOSURE_MARSHAL_CALL, I think.

When doing this, it would also make sense to add a private function
_gperl_callback_invoke_real which takes a call_exception_handlers boolean and a
list of arguments.  gperl_callback_invoke and its _trapped variant could then
convert their va_list arguments to a list and just call
_gperl_callback_invoke_real.

When this is done, we can audit the GPerlCallback users for whether they should
be switched to using the _trapped variant.
