Problem: Using freed memory when 'tagfunc' wipes out buffer that holds
'complete'.
Solution: Make a copy of the option. Make sure cursor position is valid.

Problem: no support for custom cmdline completion
Solution: Add new vimscript functions
Add the following two functions:
- getcmdcompltype() returns custom and customlist functions
- getcompletion() supports both custom and customlist

Problem: Cannot break undo by setting 'undolevels' to itself in
'inccommand' preview callback.
Solution: Don't set an invalid 'undolevels' value.
Co-authored-by: Michael Henry <drmikehenry@drmikehenry.com>
Problem: 'inccommand' doesn't restore 'undolevels' properly for a
buffer shown in multiple windows.
Solution: Don't save information of a buffer twice.
Disallow closing the previous window from `nvim_win_close`, as this will cause
issues.
Again, no telling how safe this is. It also requires exposing old_curwin. :/
Also note that it's possible for the `&cmdheight` to change if, for example,
there are 2 tabpages and `nvim_win_close` is used to close the last window in
the other tabpage while `&stal` is 1. This is addressed in a later commit.
Problem:
The cmdpreview saved undo nodes on cmdpreview_prepare() from ex_getln.c may
become invalid (free) if the preview function makes undo operations, causing
heap-use-after-free errors.
Solution:
Save the buffer undo list on cmdpreview_prepare)_ and start a new empty one. On
cmdpreview_restore_state(), undo all the entries in the new undo list and
restore the original one. With this approach, the preview function will be
allowed to undo only its own changes.

Problem:
nvim_parse_cmd() in pcall() may show an error message (side-effect):
:lua pcall(vim.api.nvim_parse_cmd, vim.fn.getcmdline(), {})
E16: Invalid range
Solution:
Avoid emsg() in the nvim_parse_cmd() codepath.
- refactor(api): add error message output parameter to get_address()
- fix: null check emsg() parameter
- refactor: remove emsg_off workaround from do_incsearch_highlighting()
- refactor: remove emsg_off workaround from cmdpreview_may_show()
- refactor: remove remaining calls to emsg() from parse_cmd_address() and get_address()
- (refactor): lint set_cmd_dflall_range()
- refactor: addr_error() - move output parameter to return value
Fix#20339
TODO:
These are the functions called by `get_address()`:
```
nvim_parse_cmd() -> parse_cmdline() -> parse_cmd_address() -> get_address()
skipwhite()
addr_error()
qf_get_cur_idx()
qf_get_cur_valid_idx()
qf_get_size()
qf_get_valid_size()
mark_get()
mark_check()
assert()
skip_regexp()
magic_isset()
> do_search()
> searchit()
ascii_isdigit()
getdigits()
getdigits_int32()
compute_buffer_local_count()
hasFolding()
```
From these functions, I found at least two that call emsg directly:
- do_search()
- seems to be simple to refactor
- searchit()
- will be more challenging because it may generate multiple error messages,
which can't be handled by the current `errormsg` out-parameter.
For example, it makes multiple calls to `vim_regexec_multi()` in a loop that
possibly generate error messages, and later `searchit()` itself may generate
another one:
- c194acbfc4/src/nvim/search.c (L631-L647)
- c194acbfc4/src/nvim/search.c (L939-L954)

Redrawing of 'statusline' and 'winbar' are actually already inhibited by
RedawingDisabled in Ex mode.
In Vim there is a check for `msg_scrolled == 0` (which is false in Ex
mode) since Vim doesn't have msgsep. Add a `!exmode_active` check here
in Nvim instead.
Removes the `getoption_T` struct and also introduces the `OptVal` struct
to unify the methods of getting/setting different option value types.
This is the first of many PRs to reduce code duplication in the Vim
option code as well as to make options easier to maintain. It also
increases the flexibility and extensibility of options. Which opens the
door for things like Array and Dictionary options.

Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.
Problem: Using freed memory with cmdwin and BufEnter autocmd.

changes only redraw from the top. (issue vim/vim#11559)

drawscreen.c vs screen.c makes absolutely no sense.
The screen exists only to draw upon it, therefore helper functions
are distributed randomly between screen.c and the file that
does the redrawing. In addition screen.c does a lot of drawing on the
screen.
It made more sense for vim/vim as our grid.c is their screen.c
Not sure if we want to dump all the code for option chars into
optionstr.c, so keep these in a optionchar.c for now.
This feature has long been obsolete. The 'keymap' option can be used
to support language keymaps, including hebrew and hebrewp (phonetic
mapping). There is no need to keep the old c code with hardcoded
keymaps for some languages.
Problem: Inserting a register on the command line does not trigger

Cherry-pick Test_Cmdline() change from patch 9.0.1039.
Problem:
The "force" flag of win_close() complicates the code and adds edge cases
where it is not clear what the correct behavior should be.
The "free_buf" flag of win_close() is passed on to float windows when
closing the last window of a tabpage, which doesn't make much sense.
Solution:
Remove the "force" flag and always close float windows as if :close! is
used when closing the last window of a tabpage, and set the "free_buf"
flag for a float window based on whether its buffer can be freed.
As 'hidden' is on by default, this change shouldn't affect many people.
