ipc-server: Acquire ownership of referenced json_object properly
When adding a referenced json_object with an unknown lifetime to
another json_object, it must be done with a wrapped call to
json_object_get() to acquire the ownership of that json_object.
After a user enters or clears a password, try to overwrite the buffer containing it. That way it's not sitting around in RAM for something else to read later. Also, mlock() the password buffer so that it is never swapped out.
This also replaces the dynamically allocated buffer with a static char[1024]. Any characters past that are discarded until the user hits enter or escape.
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.
Without unistd.h the following functions getuid, alarm and
close are implicitly declared causing compilation to fail due to
-Werror=implicit-function-declaration
When headers were installed in more sofisticated places (but package
config knows it right), it revealed missing paths in CMake
configuration. Lets fix it.
Additionally
- Made background colors display when an image is enabled if
a --color is specified.
- Link CJson to swaylock.
- Add the --socket option to swaylock.
Calling `exit` in sway_terminate prevents sway from correctly shutting
down (freeing data, cleanly terminating the ipc server, etc.).
A better way is to exit straight away if the failure occurs before
`wlc_run` and use sway_abort as usual if it occur when wlc is running.
