/*
** About 'nCcalls': each thread in Lua (a lua_State) keeps a count of
** how many "C calls" it still can do in the C stack, to avoid C-stack
** overflow. This count is very rough approximation; it considers only
** recursive functions inside the interpreter, as non-recursive calls
** can be considered using a fixed (although unknown) amount of stack
** space.
**
** The count has two parts: the lower part is the count itself; the
** higher part counts the number of non-yieldable calls in the stack.
** (They are together so that we can change both with one instruction.)
**
** Because calls to external C functions can use an unknown amount
** of space (e.g., functions using an auxiliary buffer), calls
** to these functions add more than one to the count (see CSTACKCF).
**
** The proper count excludes the number of CallInfo structures allocated
** by Lua, as a kind of "potential" calls. So, when Lua calls a function
** (and "consumes" one CallInfo), it needs neither to decrement nor to
** check 'nCcalls', as its use of C stack is already accounted for.
** About 'nCcalls': This count has two parts: the lower 16 bits counts
** the number of recursive invocations in the C stack; the higher
** 16 bits counts the number of non-yieldable calls in the stack.
** (They are together so that we can change and save both with one
** instruction.)
