	Add -Wformat-security to --enable-warnings=fatal.

	Because we use it in glibmm too. No code changes were necessary.

	Fix the build with -Wshadow.

	And add this warning to --enable-warnings=fatal.

	Require C++11

	* configure.ac: Use MM_AX_CXX_COMPILE_STDCXX_11 from mm-common to check for
	compiler support for C++11 and use it (-std=c++11 for current versions of g++).
	Among other reasons, this is because libsigc++ and glibmm now require C++11,
	and gmmproc generates C++11 code.
