was aliased to a vt sequence, causing and fixing various bugs. For syscons, this restores support for arg 2 which sets blinking block too forcefully, and restores bugs for arg 0 and 1. Arg 2 is used for vs in the cons25 entry in termcap, but I've never noticed an application that uses this. The bugs involve replacing local settings by global ones and need better handling of defaults to fix. For vt, this requires moving the aliasing code from teken to vt where it belongs. This sequences is very important for cons25 compatibility in vt since it is used by the cons25 termcap entries for ve, vi and vs. vt can't properly support vs for either cons25 or xterm since it doesn't support blinking. For xterm, the termcap entry for vs asks for something different using 12;25h instead of 25h. Rename C25CURS for this to C25LCT and change its description to be closer to echoing the old comment about it. CURS is too generic. Fix missing syscons escape sequence for setting the global cursor shape (and type). Only support this in syscons since vt can't emulate anything in it.
