* The OP_RESIZE seat operation has been renamed to OP_RESIZE_FLOATING,
and OP_RESIZE_TILING has been introduced.
* Similar to the above, seat_begin_resize and handle_resize_motion have
been renamed and tiling variants introduced.
* resize.c's resize_tiled has to be used, so container_resize_tiled has
been introduced in resize.c to allow external code to call it.
* Add and use lenient_strcat and lenient_strncat functions
* Rename `concatenate_child_titles` function as that's no longer what it
does
* Rename `container_notify_child_title_changed` because we only need to
notify that the tree structure has changed, not titles
* Don't notify parents when a child changes its title
* Update ancestor titles when changing a container's layout
* Eg. create nested tabs and change the inner container to stacking
* No need to store tree presentation in both container->name and
formatted_title
The condition checking if the markup is valid was inverted.
This commit also adds better error handling: if the markup cannot
be parsed, it fallbacks to plain text.
This starts up the event loop and wayland display and shims out the
basic top level rendering concepts. Also includes some changes to
incorporate pango into the 1.x codebase properly.
Increase _POSIX_SOURCE value where needed.
Increase _XOPEN_SOURCE value where needed.
Conditionally link to libcap (only on Linux).
Possibly some trailing whitespace fixes (automatic).
_sway_assert is a variadic function which tries
to delegate to another variadic function. This
requires a vprintf-style variant of the delegate.

Colors are configured through the command line so that swaylock conforms
to the i3lock fork 'github.com/chrjguill/i3lock-color'. Differences from
it are that one letter options '-r' and '-s' are not implimentend because
'-s' is already used by '--scaling' in swaylock.
This commit also fixed whitespace in 'include/swaylock/swaylock.h' and
changed `parse_color` in 'common/util.h' so that it can accept colors
that do not start with a hash. This was done to keep compatability with
the i3lock fork.
