Patch 8.2.0791
Problem: A second popup window with terminal causes trouble.
Solution: Disallow opening a second terminal-popup window. (closes #6101,
closes #6103) Avoid defaulting to an invalid line number.

- When the job ends, the popup window closes.
- The popup window can be closed with `popup_close()`, the terminal buffer
then becomes hidden.
- The default Pmenu color is only used for the border and padding. To change
! the color of the terminal itself set 'wincolor'.
To run a terminal in a popup window, first create the terminal hidden. Then
pass the buffer number to popup_create(). Example: >
let buf = term_start(['picker', 'Something'], #{hidden: 1, term_finish:
'close'})
let winid = popup_create(buf, #{minwidth: 50, minheight: 20})
- set wincolor=Search

- The default Pmenu color is only used for the border and padding. To change
! the color of the terminal itself set the Terminal highlight group before
! creating the terminal. Setting 'wincolor' later can work but requires the
! program in the terminal to redraw everything.
! - The default minimal size is 5 lines of 20 characters; Use the "minwidth" and
! "minheight" parameters to set a different value.
! - The terminal size will grow if the program running in the terminal writes
! text. Set "maxheight" and "maxwidth" to restrict the size.

If you want to create a new buffer yourself use |bufadd()| and pass the buffer
number to popup_create().
! It is not possible to use the buffer of a terminal window. *E278*
The second argument of |popup_create()| is a dictionary with options:
line Screen line where to position the popup. Can use a
number or "cursor", "cursor+1" or "cursor-1" to use
the line of the cursor and add or subtract a number of
! lines. If omitted the popup is vertically centered.
! The first line is 1.
When using "textprop" the number is relative to the
text property and can be negative.
col Screen column where to position the popup. Can use a
number or "cursor" to use the column of the cursor,
"cursor+9" or "cursor-9" to add or subtract a number
! of columns. If omitted the popup is horizontally
! centered. The first column is 1.
When using "textprop" the number is relative to the
