I often suppose that the functions with __ prefix is used for a kind of
(local) subroutine that mostly used internally in the *.c file, and that
therefore it is often defined as static (or static inline).

I also suppose that __Func() followed by Func() is called from Func()
(and its relatives, like Func_foo() or Func_bar() etc., if exists)
as a common core part of Func().

I thought it is acceptable since the introduced one is static.

Still I feel uneasy about the non-static __Func(), however it is
easy to fix with a little patients.
Wait a moment for next patch (it will be a single patch, v3).
