Problem: E95 is possible if a buffer called "[Command Line]" already
exists when opening the cmdwin. This can also happen if the
cmdwin's buffer could not be deleted when closing.
Solution: Un-name the cmdwin buffer, and give it a special name instead,
similar to what's done for quickfix buffers and for unnamed
prompt and scratch buffers. As a result, BufFilePre/Post are
no longer fired when opening the cmdwin. Add a "command" key
to the dictionary returned by getbufinfo() to differentiate
the cmdwin buffer instead. (Sean Dewar)
Cherry-pick test_normal changes from v9.0.0954.

Problem: Autocmds triggered from opening the cmdwin (in win_split and
do_ecmd) can cause issues such as E199, as the current checks
are insufficient.
Solution: Commands executed from the cmdwin apply to the old curwin/buf,
so they should be kept in a "suspended" state; abort if
they've changed. Also abort if cmdwin/buf was tampered with,
and check that curwin is correct. Try to clean up the cmdwin
buffer (only if hidden and non-current to simplify things; the
same approach is used when closing cmdwin normally), and add a
beep. (Sean Dewar)
Rename the old Test_cmdwin_interrupted() like in the patch (can be moved to
test_cmdwin.vim when v9.0.0027 is ported).
Move the error message to `e_active_window_or_buffer_changed_or_deleted`.

Problem: Things that temporarily change/restore curwin/buf (e.g:
win_execute, some autocmds) may break assumptions that
curwin/buf is the cmdwin when "cmdwin_type != 0", causing
issues.
Solution: Expose the cmdwin's real win/buf and check that instead. Also
try to ensure these variables are NULL if "cmdwin_type == 0",
allowing them to be used directly in most cases without
checking cmdwin_type. (Sean Dewar)
Reset and save `cmdwin_old_curwin` in a similar fashion.
Apply suitable changes for API functions and add Lua tests.

I already merged this prior, so just replace the new test with the old one,
but add a test case for the global statusline.
Problem: Using negative array index with negative width window.
Solution: Make sure the window width does not become negative.
