253f592909 Add stdin, stdout, stderr to ignored export list (Chun Kuan Lee)
fc6a9f2ab1 Use IN6ADDR_ANY_INIT instead of in6addr_any (Cory Fields)
908c1d7745 GCC-7 and glibc-2.27 compat code (Chun Kuan Lee)

Pull request description:

  The `__divmoddi4` code was modified from https://github.com/gcc-mirror/gcc/blob/master/libgcc/libgcc2.c . I manually find the older glibc version of log2f by objdump, use `.symver` to specify the certain version.
