Brian Ashworth e687e120e0 output_cmd_background: validate colors
This validates the color and fallback color in `output_cmd_background`
to ensure that only colors of the form `#RRGGBB` are accepted.

Brian Ashworth 89afb761ba output_cmd_background: fix no file + valid mode
If output_cmd_background is given a valid mode as the first argument,
then there is no file given and an error should be returned.

join_args should not be called with an argc of zero since it sets the
last character to the null terminator. With an argc of zero, the length
is zero causing a heap buffer overflow when setting the byte before the
start of argv to '\0'. This probably will not ever generate a segfault,
but may cause data corruption to whatever is directly before it in
memory. To make other such cases easier to detect, this also adds a
sway_assert in join_args when argc is zero.

M Stoeckl 1211a81aad Replace wlr_log with sway_log
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.

wlr_log_init is still invoked in sway/main.c

This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.

Don't escape swaybg arguments anymore
swaybg used to be invoked with sh, which made escaping necessary. This is no
longer necessary.

M Stoeckl 2a684cad5f Remove now-unused "input" argument of cmd_results_new
Patch tested by compiling with `__attribute__ ((format (printf, 2, 3)))`
applied to `cmd_results_new`.

String usage constants have been converted from pointers to arrays when
encountered. General handler format strings were sometimes modified to
include the old input string, especially for unknown command errors.

Brian Ashworth e5f90f25d7 Introduce a way to show config warnings in swaynag
Adds the function `config_add_swaynag_warning(char *fmt, ...)` so that
handlers can add warnings to the swaynag config log in a uniform way.
The formatting is identical to errors and include the line number, line,
and config path.

This also alters the background file access warning to use the function
and introduces a warning for duplicate bindings.

Brian Ashworth af45ee2d8b Handle shell special characters in bg file path
This changes it back so the path given to swaybg is enclosed in quotes.

Additionally, the only character that is escaped in the path stored is
double quotes now. This makes it so we don't need to keep an exhaustive
list of characters that need to be escaped.

The end user will still need to escape these characters in their config
or when passed to swaybg.

Brian Ashworth 17fe8924f2 Address ianyfan's comments
wordexp p is now initialized to {0} to prevent a segfault on wordfree
in the failure case.

File paths with single quotes and double quotes are now supported. The
quote can either be wrapped in the other quote or escaped with three
backslashes.

Additionally to make passing file paths with double quotes to swaybg
easier, instead of enclosing the path given to swaybg in quotes, all
spaces, single quotes, and double quotes in the resulting path are now
escaped with a single backslash.

Brian Ashworth 43d1ffc9dd Allow a fallback color to be specified for swaybg
This allows for a color to be set when the wallpaper does not fill the
entire output. If specified, the fallback color is also used when the
image path is inaccessible.

cleanup output-background subcommand handling
- fixes a double-free error when access() failed.

- refactor code to make memory managment (alloc/free) more straightforward
   - do not bring the temporary wordexp_t struct around
   - do not postpone errors handling

fix memleak on background cmd error
- src must be free after join_args()
- wordfree must bee used after wordexp

ael-code ad085c1332
bugfix: avoid access after free
if src is NULL due to a previous error we cannot use it in the command
result string.

Moreover if `src` points to `p.we_wordv[0]` we cannot use it after
`wordfree(&p)` in the command result string.

Bonus feature: If there was an error accessing the file, the string
rapresentation of the error is now included in the command result
string.
