* Added support for signal handling, using a new class called signal_set. Programs may add one or more signals to the set, and then perform an async_wait() operation. The specified handler will be called when one of the signals occurs. The same signal number may registered with multiple signal_set objects, however the signal number must be used only with Asio. * Added handler tracking, a new debugging aid. When enabled by defining BOOST_ASIO_ENABLE_HANDLER_TRACKING, Asio writes debugging output to the standard error stream. The output records asynchronous operations and the relationships between their handlers. It may be post-processed using the included [^handlerviz.pl] tool to create a visual representation of the handlers (requires GraphViz). * Fixed a bug in asio::streambuf where the consume() function did not always update the internal buffer pointers correctly. The problem may occur when the asio::streambuf is filled with data using the standard C++ member functions such as sputn(). (Note: the problem does not manifest when the streambuf is populated by the Asio free functions read(), async_read(), read_until() or async_read_until().) * Fixed a bug on kqueue-based platforms, where reactor read operations that return false from their perform() function are not correctly re-registered with kqueue. * Modified the buffers_iterator<> and ip::basic_resolver_iterator classes so that the value_type typedefs are non-const byte types.
