Reject requests for WM_STATE_ICONIC
For compatiblity reasons, Wine will request iconic state and cannot
ensure that the WM has agreed on it; immediately revert to normal to
avoid being stuck in a paused state.

it appears that SnDisplay can't be NULL, so I skipped the check.
Now clicks begin at the start of the "actual" block, offsets and
separators don't trigger click events. The width property is now just
the width of the block, including border.
- Add routine that will refocus the expected window on test failure.
Thus, failure on one test will not make others fail.
- Remove some redundant commands, prefer fresh_workspace for screen
changing.
- Kill previous windows between sections if the next section does not
depend on the previous layout.
- Improve / add various error messages.
- Replace all `LOG(…); ysuccess(false);` with `yerror(…);`.
- switch_mode: Remove redundant "ERROR:" ELOG string.
- cmd_move_con_to_workspace*: Make sure that we don't try to move an
empty workspace to another workspace. This can be problematic when we
match a workspace using command criteria (eg marks) and the target is a
non-existing workspace. We create the new workspace but since nothing is
moved there, we are left with an empty workspace. See added testcase.
Modified section on the layout file's non-compliance with the JSON
standard. The section previously stated that having multiple top-level
JSON texts is non-compliant. This isn't the case. It's just that most
JSON parsers will treat that as if it is non-compliant.
tree_append_json: Allow strings that are not valid UTF8
Fixes #3156.
I couldn't reproduce the problem in a "natural" way so I cheated:
1. Start i3 with gdb
2. Set breakpoing on tree_restore
3. Run, open window, i3-msg restart
5. Open the file in *path with a hex editor
6. Edit the "name" field of the window and insert bytes that are not
valid UTF8
7. Continue
After parsing fails, all nodes including croot are incomplete, meaning
they have to be deleted. We can't recover in any reasonable way so we
have to allow non-UTF8 characters to avoid this situation altogether.

Make cmd_resize_tiling_direction work with pixels
Introduces resize_neighboring_cons in resize.c which is also used by
resize_graphical_handler.
Co-authored-by: Andrew Laucius <andrewla@gmail.com>
Authored original code and tests in #3240. I rewrote most of the
resizing code and fixed the failing tests.

Introduce con_get_fullscreen_covering_ws
This commit will also fix the following bugs:
1. click.c: Users could drag global fullscreen floating containers.
2. render.c: Floating containers would get rendered with a global fullscreen container in another
workspace.

render_root: fix popup_during_fullscreen logic
The first issue is that there seems to be a typo: fullscreen->window
should have been child->window. The corrected check is redundant since
the while loop checks if the transient_con has a window.
The second issue is that popup_during_fullscreen is never checked even
though the behaviour should be exclusive to the "smart" option.

Call dragloop callback on DRAG_SUCCESS
A race condition is possible. For example, if we first receive a
XCB_MOTION_NOTIFY event and then, while drain_drag_events is still
running, a XCB_BUTTON_RELEASE event the first event is never handled
because we return.

floating_drag_window: return on DRAG_REVERT
Right now tree_render() is called twice on DRAG_REVERT since
floating_reposition calls it.
Also, on DRAG_REVERT the scratchpad state shouldn't change since the
user canceled the action.
Kill misbehaving subscribed clients instead of hanging
This change only affects clients that are subscribed to events, which
should be the main cause of our problems.
In the common case (no buffered data) the behaviour doesn't change at
all: the message is sent directly, no ev_io / ev_timeout callback is
enabled. Once a write to a client's socket is not completed fully
(returns with EAGAIN error), we put the message in the tail of a queue
and init an ev_io callback and a corresponding timer. If the timer is
triggered first, the socket is closed and the client connection is
removed. If the socket becomes writeable before the timeout we either
reset the timer if we couldn't push all the buffered data or completely
remove it if everything was pushed.
We could also replace ipc_send_message() for all client connections in
i3, not just those subscribed to events.
Furthermore, we could limit the amount of messages stored and increase
the timeout (or use multiple timeouts): eg it's ok if a client is not
reading for 10 seconds and we are only holding 5KB of messages for them
but it is not ok if they are inactive for 5 seconds and we have 30MB of
messages held.
This commit makes multiple changes in tree_close_internal. I didn't
split them because they are not completely independent.
- Remove force_set_focus parameter
This parameter was always set to `false` throughout the code base except
for one case where it was set to `(con == focused)`, when killing a
floating con's parent (the one with type CT_FLOATING_CON). But this case
is not needed anymore since the special handling of CT_FLOATING_CONs in
con_next_focused was removed in #2941.
- Assume that con_next_focused does not returned a container of type
CT_DOCKAREA. This is reasonable since con_next_focused uses the
focus_head stack and has special handling of CT_DOCKAREA containers.
- Remove is_mapped
This variable was only used in the if block towards the end of
tree_close_internal. Ignoring the, now removed, dockarea code and the
use of force_set_focus this block performed only one useful action:
focus the `next` container when `con == focused`. `con == focused` was a
necessary and sufficient condition for the con_activate call:
if `con != focused` we could reach the inner if blocks because of the
other conditions but would never focus another container. If `con ==
focused` then all other conditions would be irrelevant.
- Remove special handling of floating containers
Since the `next` focused container is calculated through the parent for
floating containers, I moved this code to con_next_focused.
Also, because of the removal of force_set_focus, it appears that we can
call con_on_remove_child for floating containers as well.
