Problem: When clicking in the middle of a TAB, getmousepos() returns
the column of the next char instead of the TAB.
Solution: Break out of the loop when the vcol to find is inside current
char. Fix invalid memory access when calling virtcol2col() on
an empty line.

Problem: screenpos() wrong result with w_skipcol and cpoptions+=n

Problem: missing winid argument for virtcol()
Solution: Add a {winid} argument to virtcol()
Other functions col(), charcol() and virtcol2col() support a {winid}
argument, so it makes sense for virtcol() to also support than.
Also add test for virtcol2col() with 'showbreak' and {winid}.

Problem: screenpos() returns wrong row with diff filler lines.
Solution: Only add filler lines when appropriate. Also don't add the
'smoothscroll' marker when w_skipcol is zero. (closes#12485,
closes#12484)
Problem: col() and charcol() only work for the current window.
Solution: Add an optional winid argument. (Yegappan Lakshmanan,
closes#11466, closes#11461)
Problem: Wrong column when calling setcursorcharpos() with zero lnum.
Solution: Set the line number before calling buf_charidx_to_byteidx().
(closes#11329)
Problem: screenpos() is wrong when the last line is partially visible and
'display' is "lastline".
Solution: Also compute the position for a partially visible line.
(closes#8599)
Problem: "char" functions return the wront column in Insert mode when the
cursor is beyond the end of the line.
Solution: Compute the column correctly. (Yegappan Lakshmanan, closes#7669)
Problem: Not easy to get mark en cursor posotion by character count.
Solution: Add functions that use character index. (Yegappan Lakshmanan,
closes#7648)
Problem: Using old function name in comment. More functions should start
with test_.
Solution: Rename function in comment. (Higashi Higashi) Rename
disable_char_avail_for_testing() to test_disable_char_avail().
And alloc_fail() to test_alloc_fail().
