Re: [PATCH 1/5] vt: Add cursor-size helpers

Cursors in the VT subsystem are blocks within a character cell that are
filled with the foreground color. The new helpers vc_font_cursor_start()
and vc_font_cursor_end() return the scanlines in which the cursor block
starts rsp. ends. This is compatible with VGA hardware

In terms of cursor design, the new cursor-size helpers follow established
styles in fbcon. The only exception is in underline cursors for fonts with
a size larger than 10. The underlining dash is now one pixel closer to
the font-glyph data, so that the cursor looks less detached. This follows
the style used by vgacon.

Similar code in vgacon and fbcon ignores the cursor's default size stored
in vt.cur_default. The consoles default to full-block cursors, while vt
defaults to underline cursors. The new helper fall back to cur_default and
then underline cursors; in this order.
