vfs_select.h, respectively moved most of it into the new kernel private header wait_for_objects.h. * Added new experimental API functions wait_for_objects[_etc](). They work pretty much like poll(), but also for semaphores, ports, and threads. * Removed the "ref" parameter from notify_select_events() and the select_sync_pool functions as well as from fd_ops::fd_[de]select(). It is no longer needed. The FS interface select() hook still has it, though -- the VFS will always pass 0. * de]select_fd() take a select_info* instead of a select_sync* + ref pair, now. Added respective functions for semaphores, ports, and threads. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22416 a95241bf-73f2-0310-859d-f6bbb57e9c96
