Don't lose top specpdl entry when memory is exhausted.

* eval.c (grow_specpdl): Increment specpdl top by 1 and check for
specpdl overflow here, to simplify callers; all callers changed.
Always reserve an unused entry at the stack top; this avoids
losing the top entry's information when memory is exhausted.
