Chmod used to incorrectly report as changed even files for which the
mode did not change. This was caused by extra bits in the st_mode, that
were not present when parsed from passed argument in the form of octal
number.

Allow ISO 8601 style dates to include a timezone offset. Like
the '@' format these dates aren't relative to the user's current
timezone and shouldn't be subject to DST adjustment.
- The implementation uses the strptime() '%z' format specifier.
This an extension which may not be available so the use of
timezones is a configuration option.
- The 'touch' applet has been updated to respect whether DST
adjustment is required, matching 'date'.

A user noted that the following command was slower than they
expected:
busybox shuf -i "1500000000-$(date +%s)" -n 5
At time of writing the range contains 128 million values. On my
system this takes 7.7s whereas 'shuf' from coreutils takes a
handful of milliseconds.
Optimise BusyBox 'shuf' for cases where -n is specified by stopping
shuffling once the required number of lines have been processed.
On my system the time for the example is reduced to 0.4s.

v2: Code shrink. Since outlines <= numlines:
- the loop in shuffle_lines() only needs to test the value of
outlines;
- shuffle_lines() can be called unconditionally.
Update timing to allow for the 13 million seconds elapsed since v1.

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.
