Rename mark_stack to mark_c_stack

This is the function that marks the C stack.  Avoid confusion with the
new mark stack, a stack used in the GC mark phase.

* src/alloc.c (SETJMP_WILL_LIKELY_WORK, SETJMP_WILL_NOT_WORK)
(mark_stack, mark_c_stack):
* src/lisp.h:
* src/thread.c (mark_one_thread): Rename mark_stack to mark_c_stack.
