* New maybe_const_t alias for maybe_const * New asio::enable_wait_for_async for safe cleanup * New asio::memory_buffer, a managed boost::asio compatible buffer * shared_handler improvements: - Can be 'empty' (no stored handler). - Default constructible as 'empty'. - Safe evaluation in bool contexts, false==empty * Fix is_call_possible metafunction: - Works on empty argument lists - Works with reference types * Replace SafeBool idiom with C++11 explicit operator bool * Move IPAddress function definitions to the header * Move cyclic_iterator to container/ * Remove unused BufferType * Remove obsolete classes: - NamedPipe - ReadWriteLock - ScopedReadLock - ScopedWriteLock - LockGuard
