busybox: update to version 1.34.0

Update busybox to version 1.34.0

* Remove upstreamed patches (205, 530, 540)

* Remove one old patch that does not apply any more. (203)
  That was originally introduced in 2008 with 563d2345,
  but does not apply after busybox restructuring with
  https://git.busybox.net/busybox/commit/networking/udhcp/dhcpc.c?h=1_34_stable&id=e6007c4911c3ea26925f9473b9f156a692585f30
  and
  https://git.busybox.net/busybox/commit/networking/udhcp/dhcpc.c?h=1_34_stable&id=1c7253726fcbab09917f143f0b703efbd2df55c3

* Refresh config and patches.

* Backport upstream fixes for
   - MIPS compilation breakage and
   - process substitution regression

Config refresh:

Refresh commands, run after busybox is first built once:

cd utils/busybox/
cd config/
../convert_menuconfig.pl ../../../../build_dir/target-aarch64_cortex-a53_musl/busybox-default/busybox-1.34.0
cd ..
./convert_defaults.pl < ../../../build_dir/target-aarch64_cortex-a53_musl/busybox-default/busybox-1.34.0/.config > Config-defaults.in

Manual edits needed afterward:

* Config-defaults.in:  OpenWrt config symbol IPV6 logic applied to
  BUSYBOX_DEFAULT_FEATURE_IPV6
* Config-defaults.in:  OpenWrt configTARGET_bcm53xx logic applied to
  BUSYBOX_DEFAULT_TRUNCATE (commit 547f1ec2)
* Config-defaults.in:  OpenWrt logic applied to
  BUSYBOX_DEFAULT_LOGIN_SESSION_AS_CHILD (commit dc929174)
  BUSYBOX_DEFAULT_UDHCPC_DEFAULT_INTERFACE (just "")
* config/editors/Config.in: Add USE_GLIBC dependency to
  BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commit f1410902)
* config/shell/Config.in : change at "Options common to all shells"  the symbol
  SHELL_ASH  -->  BUSYBOX_CONFIG_SHELL_ASH
   (discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html


     Apparently our script does not see the hidden option while
     prepending config options with "BUSYBOX_CONFIG_" which leads to a
     missed dependency when the options are later evaluated.)
* Edit Config.in files by adding quotes to sourced items in
  config/Config.in, config/networking/Config.in and config/util-linux/Config.in (commit 1da014fc)

package/utils/busybox/patches/002-backport-ash-process-substitution.patch

+Stacy Harper reports that this script:
+
+   test() { . /tmp/bb_test; }
+   echo "export TEST=foo" >/tmp/bb_test
+   test 2>/dev/null
+   echo "$TEST"
+
+correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34.
+
+Bisection suggested the problem was caused by commit a1b0d3856 (ash: add
+process substitution in bash-compatibility mode).  Removing the call to
+unwindredir() in cmdloop() introduced in that commit makes the script
+work again.
+
+Additionally, these examples of process substitution:
+
+   while true; do cat <(echo hi); done
+   f() { while true; do cat <(echo hi); done }
+   f
+
+result in running out of file descriptors.  This is a regression from
+v5 of the process substitution patch caused by changes to evalcommand()
+not being transferred to v6.

-From 7eed119b84b0f7efb7ef351940dd895dc2379eb3 Mon Sep 17 00:00:00 2001
-From: Russell Senior <russell@personaltelco.net>
-Date: Mon, 15 Mar 2021 23:27:58 -0700
-Subject: [PATCH v2] udhcpc: ignore zero-length DHCP options
-
-Discovered that the DHCP server on a TrendNet router (unknown model)
-provides a zero-length option 12 (Host Name) in the DHCP ACK message. This
-has the effect of causing udhcpc to drop the rest of the options, including
-option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server),
-most importantly leaving the OpenWrt device with no default gateway.
-
-The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that
-option 12 has a miniumum length of 1 octet. It is perhaps not a cosmic coincidence
-that I found this behavior on Pi Day.
-
-This patch allows zero length options without bailing out, by simply skipping them.
-
-v2 changelog:
-* advance the optionptr by two bytes, not one;
-* add a message to warn about the rfc violation;

package/utils/busybox/patches/530-use-SOURCE_DATE_EPOCH-for-timestamp-if-available.patch

-Subject: [PATCH] use SOURCE_DATE_EPOCH for timestamp if available
-
-The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds
-organization to make timestamps/build dates in compiled tools
-deterministic over several repetitive builds.
-
-Busybox shows by default the build date timestamp which changes whenever
-compiled. To have a reasonable accurate build date while staying
-reproducible, it's possible to use the *date of last source
-modification* rather than the current time and date.
-
-Further information on SOURCE_DATE_EPOCH are available online [1].
-
-This patch modifies `confdata.c` so that the content of the
-SOURCE_DATE_EPOCH env variable is used as timestamp.
-
-To be independent of different timezones between builds, whenever
-SOURCE_DATE_EPOCH is defined the GMT time is used.

-SRV lookups are supported since "6b4960155 nslookup: implement support
