ls: don't output any colors with TERM=dumb
...
The TERM variable is usually set to "dumb" to indicate that the terminal
does not support any ANSI escape sequences. Presently, ls does not honor
this variable and outputs colors anyhow which results in unreadable
output, unless the user explicitly disables colors using `ls
--color=never`. The rational behind this change is that ls should "just
work" by default, even on dumb terminals.
For this reason, this patch adds a check which additionally consults the
TERM variable before printing any colors. This is analogous to the
existing check for ensuring that standard output is a tty. As such,
colors can still be forced with `--color=force`, even if TERM is set to
dumb.

libbb: fix '--help' handling in FEATURE_SH_NOFORK=y
...
Most BusyBox applets respond to the '--help' option by printing
a usage message. This is normally handled by busybox_main() so
applet main routines don't have support for '--help'.
In standalone shell mode with FEATURE_SH_NOFORK enabled nofork
applets are invoked directly, bypassing busybox_main(). This
results in inconsistent handling of '--help':
- applets which call getopt() report "unrecognized option '--help'"
and print help anyway;
- realpath says "--help: No such file or directory" and doesn't
print help;
- usleep says "invalid number '--help'" and doesn't print help.
Avoid inconsistency by checking for '--help' in run_nofork_applet().
Bug found by Ron Yorston.

mount: support the sizelimit and offset option for loop devices
...
Starting with linux kernel v5.4 squashfs has a more strict parameter
checking implemented. Unlike util-linux mount, busybox never supported
the sizelimit option but simply forwards it to the kernel.
Since v5.4 mounting will fail with
squashfs: Unknown parameter 'sizelimit'
Support the sizelimit parameter by setting it in the LOOP_SET_STATUS64
structure before handing it to the kernel.
While at it also add support for the offset option, which currently will
always be set to 0.
