Unfortunately we cannot indiscriminately replace xfree() with
XFREE_CLEAR(), because comparing pointers after freeing them is a common
pattern. Example in `tv_list_remove_items()`:
xfree(li);
if (li == item2) {
break;
}
Instead we can do it selectively/explicitly.

- redraw! in an invisible buffer rendered the screen unusable.
- storing the autocmd window handle and using it in API function could lead
to crashes. Unregister the handle when the window is not active.
Problem: If autocmd pattern only contained `++once` handlers, and
all of them completed, then there would be an empty group
displayed by `:autocmd Foo`.
Solution: Delete the pattern if all of its commands were deleted.
Adds a new feature to :autocmd which sets the handler to be executed at
most one times.
Before:
augroup FooGroup
autocmd!
autocmd FileType foo call Foo() | autocmd! FooGroup * <buffer>
augroup END
After:
autocmd FileType foo once call Foo()

ref #9028
If stdin closed then read_error_exit calls preserve_exit. Handling
SIGHUP during preserve_exit would cause a premature teardown, and
conflicts with e.g. ui_bridge_stop which waits for TUI to teardown.
Vim ignores SIGHUP in its prepare_to_exit and getout_preserve_modified
routines:
/* Ignore SIGHUP, because a dropped connection causes a read error, which
* makes Vim exit and then handling SIGHUP causes various reentrance
* problems. */
signal(SIGHUP, SIG_IGN);
1. Don't check elapsed time in children_kill_cb(), it's already implied
by the start-time of the timer itself.
2. Restart timer from children_kill_cb() for PTY jobs, to send SIGKILL
after SIGTERM. There is an edge case where SIGKILL might follow
SIGTERM too quickly, if jobstop() is called near the 2-second timer
window. But this edge case is not worth code complication.
Implement nvim_command_output with `execute({cmd},"silent")`.
Behavior changes:
- does not provoke any hit-enter prompt
- no longer prepends a newline char
- does not capture some noise (like the "[New File]" message, see the
change to tabnewentered_spec.lua)
Technically ("bug-for-bug") this a breaking change. But the previous
behavior of nvim_command_output meant that it probably wasn't used for
anything outside of tests.
Also remove the undocumented `v:command_output` variable which was
a hack introduced only for the purposes of nvim_command_output.

Problem: after a help window was closed, a window was selected and its
autocommands triggered. After that, restore_snapshot was called and the
focused window changed, confusing the user.
Solution: Add function get_snapshot_focus() that returns the window that
holds the cursor in a snapshot. Use this function in win_close to make
sure the right window is selected before any autocommand is triggered.

patch 8.0.1206: no autocmd for entering or leaving the command line
Problem: No autocmd for entering or leaving the command line.
Solution: Add CmdlineEnter and CmdlineLeave.

Hope this will make people using feed_command less likely: this hides bugs.
Already found at least two:
1. msgpackparse() will show internal error: hash_add() in case of duplicate
keys, though it will still work correctly. Currently silenced.
2. ttimeoutlen was spelled incorrectly, resulting in option not being set when
expected. Test was still functioning somehow though. Currently fixed.
Let the terminal dictate the normal-mode cursor position. This will be
disorienting sometimes, but it is closer to what users expect vs always
going to the last line.
