Split the common part into a function, to be reused.
The tail call is optimized, meaning now mmin/mtime just prepare arguments
and jump into the common code, thus near zero overhead.
This reduces code size slightly, e.g. on x86_64:
text data bss dec hex filename
4806 0 0 4806 12c6 findutils/find.o.orig
4782 0 0 4782 12ae findutils/find.o
Of course, the savings are even greater when implementing atime/ctime
variants.

Add the --post-file option to send form data from a file. As with
--post-data it's up to the user to ensure that the data is encoded
as appropriate: all wget does is stuff the provided data into
the request.
The --post-data and --post-file options are mutually exclusive and
only one instance of either may be given.
Additionally:
- update the usage message to include missing details of the --post-data
and --header options;
- free POST data if FEATURE_CLEAN_UP is enabled.

Commit 9fe1548bb (date,touch: allow timezone offsets in dates)
mentioned the similarity between '@' format dates and those with
timezone offsets. It didn't notice that as a result there's
common code which can be shared.

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'.

The default build uses strptime() in parse_datestr() to support the
'month_name d HH:MM:SS YYYY' format of GNU date. If we've linked
with strptime() there's an advantage is using it for other formats
too.
There's no change to the non-default, non-DESKTOP build.

Commit fb7d6c89 from Harald van Dijk's gwsh variant of ash
(https://github.com/hvdijk/gwsh):
ignoreeof is documented as only having an effect for interactive shells,
but is implemented as having mostly the same effect for interactive
shells as for non-interactive shells. Change the implementation to match
the documentation.
Test case:
$SHELL -o ignoreeof /dev/null

When the user tries to exit an interactive shell with stopped jobs
present the shell issues a warning and only exits if the user
insists by trying to exit again.
This shouldn't apply to non-interactive shells.

The ignoreeof option should prevent an interactive shell from
exiting on EOF. This hasn't worked in BusyBox ash since commit
727752d2d (ash: better fix for ash -c 'echo 5&' and ash -c 'sleep 5&'
with testcase).
Commit 3b4d04b77e (ash: input: Allow two consecutive calls to pungetc)
pulled in improved support for multiple calls to pungetc from dash,
thus rendering much of commit 727752d2d obsolete. Removing this old
code fixes the problem with ignoreeof.
