Reframe swallowed windows if depth doesn't match
X will not allow a window with ParentRelative background to be created
or reparented under a window with mismatching color depth.
Deal with this by destroying the container frame and creating a new one
with the right depth upon swallowing.
Defer destruction of the frame window until after the updated tree has
been rendered to avoid some distracting flickering.

Replace strncpy call with memcpy when result is not NUL-terminated
This fixes a new warning from GCC 8.1, -Wstringop-truncation:
https://gcc.gnu.org/gcc-8/changes.html
https://gcc.gnu.org/onlinedocs/gcc-8.1.0/gcc/Warning-Options.html#index-Wstringop-truncation
Replacing with memcpy is what gcc suggests:
> As another example, the following call to strncpy results in copying
> to d just the characters preceding the terminating NUL, without
> appending the NUL to the end. Assuming the result of strncpy is
> necessarily a NUL-terminated string is a common mistake, and so the

Activate the focused child when scrolling over tab/stack decorations
fbce834b introduced a bug where scrolling over the decoration while
another container is focused would not focus the tabbed/stacked
container itself, but would instead move focus through the currently
focused container.

Don't refocus a workspace cleaned up by `workspace_show` during rename
When moving a workspace to the current output by way of a rename, if the
current workspace is empty, it will be removed by `workspace_show`.
Attempting to restore focus to this removed workspace causes a crash.
Follow the pattern in workspace.c:996 to only restore the original focus if the
original workspace still exists.
Add a test to ensure that the renamed workspace moves to its appropriate
output and that a crash does not occur.
Fix: ConfigureNotify can crash i3 with fake-outputs
handle_screen_change() and handle_configure_notify() call
randr_query_outputs() where root_output is not initialized because
randr_init() is never called when config.fake_outputs is not NULL.
Don't call con_fullscreen_permits_focusing with ignore_focus
When we don't modify the focus we aren't risking giving focus to a
container behind the current fullscreen one.
_con_move_to_con can with ignore_focus is called through the swap
command or through con_move_to_workspace for floating containers. This
change shouldn't break the expectations of the callers there.
This is enough to fix the crash discussed in #3259 even though the next
commit can fix it independently. This commit is useful because it
generally makes sense to abort the command when the first call to
_con_move_to_con fails.
- 'border toggle' now accepts an optional pixel argument which will be
ignored when switching to BS_NONE.
- 'border pixel' now defaults to 1 pixel instead of 2.
- Calling 'border normal' or 'border pixel' will use the configured
default_border_width if one exists. Also applies to floating windows.
i3bar: don't reset verbosity when parsing config values
When i3bar is called with the -V flag but there is no 'verbose yes'
directive in the bar {} config, the verbosity config value is reset.
This will introduce the opposite, negligible issue: you can't disable
i3bar's verbosity by deleting the 'verbose yes' directive in the bar {}
config. To fix this we would need an enum for config.verbose.

Workspace renaming: Interpret outputs as nondirectional
Currently when renaming outputs, an output assignment of "left" will
cause the workspace to move left. Treat this assignment as a proper name
instead (even though it is unlikely an output will be named "left").
Move logic for determining output to move to out of
`workspace_move_to_output`
Add test for ignoring direcionality during rename.
Prefer compiler warnings to assertions for unhandled switch cases
Using 'default:' cases can hide logical errors which would lead to i3
crashes for users. With this change the compiler will print a warning
when a case is not handled. For example, if I add a new value in the
Font.type enum:
../../i3/libi3/font.c: In function ‘draw_text’:
../../i3/libi3/font.c:378:5: warning: enumeration value ‘NEWFONT’ not handled in switch [-Wswitch]

Window decoration scrolling: don't focus sibling
The current behaviour is buggy in the following layout:
T [ A* V [ B C ] ], where the focus stack in V is B > C.
When the user scrolls down, focus correctly moves to B but if the user
scrolls down again the whole vertical container is focused.
This happens because 'bool scroll_next_possible' is false but
con_activate is called on the tabbed container's sibling - the vertical
container.
i3bar’s X11 output is not what our testcases are testing — the state
manipulations which i3bar triggers via IPC messages to i3 are what we are
interested in.
Sending the sync command via IPC ensures pending IPC messages are handled by i3
before the sync response is read. This is rarely useful for direct IPC
connections to i3, but becomes useful when synchronizing with i3bar, which might
have pending IPC messages in response to button clicks.
Remove special handling of floating containers in con_next_focused
Explanation for the changed test:
After $third is switched to floating, the test moves focus to $second.
So, the parent of $second (the stacked container) is above $third in the
focus stack and it's children ($first, $second) should get focused
before $second. When $second is switched to floating the correct focus
order for the workspace should be $second->parent (floating con is the
parent) > $first->parent (stacked con) > $third.
2. Run `python2 ./xproperty.py _XKB_RULES_NAMES ''` (from
https://github.com/siemer/xproperty) in the xinitrc
3. Memory sanitizers detect memory leaks.
Note: We don't (and didn't) pass NULL in xkb_keymap_new_from_names() but
an xkb_rule_names structures with NULL fields (fill_rmlvo_from_root only
fills its argument when there are no errors) should be equivalent:
https://github.com/xkbcommon/libxkbcommon/blob/767fa86d42a5e25e7043622d189247e02a5ca379/NEWS#L349-L351
> The function xkb_keymap_new_from_names() now accepts a NULL value for
the 'names' parameter, instead of failing. This is equivalent to passing
a 'struct xkb_rule_names' with all fields set to NULL.

Fix potential memory leak
xkb_state_new uses calloc and may fail in a rare case, which would cause a memory leak.
Note that xkb_state_unref checks if the parameter given is not null (!state) before freeing.
Calls to xkb_state_new have been grouped to remove code duplication.
con_next_focused uses con's parent. But since con can be inside an
unfocused container this means that one of it's siblings could become
focused in the current workspace.
