Removes the wlroots dependency from the common code. To remove the
dependency on the header, the defines and log-level enum are copied
over.
This causes a redefine error if both the wlr and the sway log.h are
included.
Moves input handling code that uses headers from wlroots from the common
code to sway proper, to allow for removing the wlroots dependency from
clients
Introduce the sway_log functions as equivalents of the wlr_log
functions. This is a first step to free clients from the wlroots
dependency and allows to use the sway source path for file path
stripping which should get nicer __FILE__ cleans.
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.
