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.

Chmod used to incorrectly report as changed even files for which the

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.

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

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.

BusyBox on Termux can't use ports less than 1024 it's patched to change default port for httpd to 8080 and telnetd to 8023.

https://github.com/termux/termux-packages/blob/master/packages/busybox/0010-networking-httpd-default-port.patch
To avoid such patches we can make port configurable.

Commit 7d06d6e18 (awk: fix printf %%) can cause awk printf to read
beyond the end of a strduped buffer:
2349 while (*f && *f != '%')
2350 f++;
2351 c = *++f;
If the loop terminates because a NUL character is detected the
character after the NUL is read. This can result in failures
depending on the value of that character.

Upstream commit:
Date: Wed, 27 May 2020 12:19:13 +1000
parser: Get rid of PEOA
PEOA is a special character used to mark an alias as being finished
so that we don't enter an infinite loop with nested aliases. It
complicates the parser because we have to ensure that it is skipped
where necessary and not copied to the resulting token text.
This patch removes it and instead delays the marking of aliases
until the second pgetc. This has the same effect as the current
PEOA code while keeping the complexities within the input code.
This adds ~32 bytes of global data:

Upstream commit:
Date: Wed, 29 Apr 2020 00:19:59 +1000
parser: Fix alias expansion after heredoc or newlines
This script should print OK:
alias a="case x in " b=x
a
b) echo BAD;; esac
alias BEGIN={ END=}
BEGIN
cat <<- EOF > /dev/null
$(:)
EOF
END
: <<- EOF &&
$(:)
EOF
BEGIN
echo OK
END
However, because the value of checkkwd is either zeroed when it
shouldn't, or isn't zeroed when it should, dash currently gets
it wrong in every case.
This patch fixes it by saving checkkwd and zeroing it where needed.

Adding previously skipped "readtoken1(pgetc_eatbnl(), syntax_type..." change
from upstream commit:
Date: Thu Mar 8 08:37:11 2018 +0100
parser: use pgetc_eatbnl() in more places
dash has a pgetc_eatbnl function in parser.c which skips any
backslash-newline combinations. It's not used everywhere it could be.
There is also some duplicated backslash-newline handling elsewhere in
parser.c. Replace most of the calls to pgetc() with calls to
pgetc_eatbnl() and remove the duplicated backslash-newline handling.
Testcase:
PS1='\
:::'
should result in ::: prompt, not <newline>::: prompt

This patch saves and restores the heredoclist in expandstr.
It also removes a bunch of unnecessary volatiles as those variables
are only referenced in case of a longjmp other than one started by
a signal like SIGINT.

Upstream commit:
Date: Tue, 28 Apr 2020 01:15:26 +1000
parser: Fix handling of empty aliases
Dash was incorrectly handling empty aliases. When attempting to use an
empty alias with nothing else, I'm (incorrectly) prompted for more
input:
```
$ alias empty=''
$ empty
>
```
Other shells (e.g., bash, yash) correctly handle the lone, empty alias as an
empty command:
```
$ alias empty=''
$ empty
$
```
The problem here is that we incorrectly enter the loop eating TNLs
in readtoken(). This patch fixes it by setting checkkwd correctly.
