* Chrono support. * Added object_handle support. * Need to enable the basic_handle class when object_handle is supported. * Update copyright notices. * Fix MSVC "performance warning". * Fix for NetBSD. Fixes #6098. * Fix regression in buffered_write_stream. Fixes #6310. * Fix deadlock on Mac OS X. Fixes #6275. * On linux, connect can return EAGAIN in certain circumstances. Remap to another error so that it doesn't look like a non-blocking operation. Fixes #6048. * Fix non-paged pool "leak" on Windows when io_service is repeatedly run without anything to do. Fixes #6321. * Disable object_handle on Windows CE. * Add extra include required for OVERLAPPED struct. * Fix doxygen comments. * Update documentation. * Add missing class. * Update copyright year.
