vt(4): Adjust the cursor position after changing the window size
A new terminal_set_cursor() is added: it wraps the existing
teken_set_cursor() function.
In vtbuf_grow(), the cursor position is adjusted at the end of the
function. In vt_change_font(), we call terminal_set_cursor() just after
terminal_set_winsize_blank(), while the terminal is mute.
This fixes a bug where, after loading a kernel video driver which
increases the terminal window size, the cursor remains at its old
position, in other words, in the middle of the display content.
