Adds two undocumented v: variables: _null_list and _null_dict because I do not
know a reproducible way to get such lists (though I think I heard about this)
and dictionaries (do not remember hearing about them). NULL strings are obtained
using $XXX_UNEXISTENT_VAR_XXX.
Fixes crash in json_encode($XXX_UNEXISTENT_VAR_XXX). Other added tests worked
fine before this commit.
Compiler used by one VM in QuickBuild has found a number of false positives.
Everything is fine on travis.
List of failures:

, pointing to `:` in `{char} = ({char} == {const} ? {const} : {char})` where
`{const}` is character constant like `'\n'`. I have no idea where exactly it saw
conversion, so simply casted everything to (char).

Reasons:
- One does not have to do `s[len] = NUL` to work with these functions if they do
not need to replace the whole string: thus `s` may be const.
- One does not have to save/restore p_cpo to work with them.
A wrong format specifier and not enough allocated memory for
sourcing_name could lead to a heap corruption.
Original patch by Rui Abreu Ferreira (@equalsraf)
Fixes#4582
Prior to this change, type errors were silently ignored. They're explicit now.
setqflist(list, action, title)
setloclist(win, list, action, title)
"list" (required) must be a list.
"action" (optional) must a string.
"title" (optional) must a string or number that gets converted to a string.
An error is thrown otherwise.
Problem: Typo in test goes unnoticed.
Solution: Fix the typo. Give error for wrong arguments to cursor().
(partly by Hirohito Higashi) Add a test for cursor().

Problem: searchpos() always starts searching in the first column, which is
not what some people expect. (Brett Stahlman)
Solution: Add the 'z' flag: start at the specified column.

Problem: When using slices there is a mixup of variable name and namespace.
Solution: Recognize variables that can't be a namespace. (Hirohito Higashi)

All syntastic users experienced this problem:
E685: Internal error: get_tv_string_buf()
It's reproducable with:
:call setloclist(0, [''])
So, not given optional arguments to setloclist() lead to some fields not
inizilied and the code took the wrong branches.
Add an extra argument to these functions to set w:quickfix_title.
