named_condition.hpp does not compile

[yusuke_mitsuki@…]

named_condition::wait() causes the compile error with msvc8.

   namespace ip = boost::interprocess;

    ip::interprocess_mutex mtx;
    ip::named_condition cond(ip::create_only, "Test");
    ip::scoped_lock<ip::interprocess_mutex> lock(mtx);

    cond.wait(lock); // error

The documentation says:

"A global condition variable that can be created by name. This condition variable is designed to work with named_mutex and can't be placed in shared memory or memory mapped files."

So a named condition variable can't be used with interprocess_mutex. The documentation of wait functions mentions interprocess_mutex so the documentation of those functions is wrong.

Fixed documentation and added compile-time static assertion.
