- mark BeOS-specific ioctls we support for legacy apps,

Browse Source 
- add 'wsiz' which is a private alias for TIOCSWINSZ,
- add some we might want to implement (or not) as reminder,
- add hw signal ioctls with a note for later (call driver service func),
- implement 'ichr' undocumented ioctl that waits on N chars on input, this fixes behaviour of rhapsody IRC client and many other curses apps. Oddly it seems even our own curses still uses it, that should likely be fixed as we support select(). But we must keep this one in to support apps that have their own curses lib.
