  Log Message:
  -----------
  compiler: Use C11 build assertions with new enough GCC or Clang.

Until now, the BUILD_ASSERT and BUILD_ASSERT_DECL macros have used OVS's
home-grown build assertion strategy.  This commit switches them to using
C11 build assertions with compilers that support them.  The semantics are
the same, but C11 build assertions yield clearer error messages when they
fail.

This commit also reorders the definitions a bit to make it easier to
follow.
