Changeset 3581 for trunk/configure.ac

Message:

refs #878

Make configure try to turn on compiler switches (such as -std=c++11),
so it supports rvalues. If found, #define YAT_HAVE_RVALUE, which can
be used both in source files and in header files. For header files,
<yat/utility/config_public.h> must be #included.

As detailed in README users can turn off cxx11 support when at
configure time of yat, or at compile time of user's package with
preprocessor definition YAT_WITHOUT_CXX.
