Add optional GC marking function to specpdl unwind_ptr record
Add a new `record_unwind_protect_ptr_mark` function for use with C data
structures that use the specpdl for clean-up but also contain possibly
unique references to Lisp objects.
* src/eval.c (record_unwind_protect_ptr_mark): New.
(record_unwind_protect_module, set_unwind_protect_ptr):
Set the mark function to NULL.
(mark_specpdl): Call the mark function if present.
* src/lisp.h (unwind_ptr): Add a mark function pointer to the
SPECPDL_UNWIND_PTR case.
