busybox: update to 1.35.0

Update busybox to 1.35.0

* refresh patches

Config refresh:

Refresh commands, run after busybox is first built once:

cd package/utils/busybox/config/
../convert_menuconfig.pl ../../../../build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/busybox-default/busybox-1.35.0
cd ..
./convert_defaults.pl ../../../build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/busybox-default/busybox-1.35.0/.config > Config-defaults.in

Manual edits needed after config refresh:

* 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 547f1ec)

* Config-defaults.in: OpenWrt logic applied to
  BUSYBOX_DEFAULT_LOGIN_SESSION_AS_CHILD (commit dc92917)

* config/editors/Config.in: Add USE_GLIBC dependency to
  BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commit f141090)

* 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 1da014f)

This option makes top and ps ~20% faster (or 20% less CPU hungry),
but code size is slightly bigger.
With this option, "cp file symlink" will delete symlink
and create a regular file. This does not conform to POSIX,
but prevents a symlink attack.
Similarly, "cp file device" will not send file's data
to the device. (To do that, use "cat file >device")

Enable support for network names in /etc/networks. This is
a rarely used feature which allows you to use names
instead of IP/mask pairs in route command.

If this feature is not enabled, they will be, respectively:

This will cost you ~60 bytes.
config BUSYBOX_CONFIG_FEATURE_USE_SENDFILE
bool "Use sendfile system call"
default BUSYBOX_DEFAULT_FEATURE_USE_SENDFILE
help
Look up e.g. "telnet" and "http" in /etc/services file
instead of assuming ports 23 and 80.
This is almost never necessary (everybody uses standard ports),
and it makes sense to avoid reading this file.
If you disable this option, in the cases where port is explicitly
specified as a service name (e.g. "telnet HOST PORTNAME"),
it will still be looked up in /etc/services.
When enabled, busybox will use the kernel sendfile() function
instead of read/write loops to copy data between file descriptors
(for example, cp command does this a lot).
If sendfile() doesn't work, copying code falls back to read/write
loop. sendfile() was originally implemented for faster I/O
from files to sockets, but since Linux 2.6.33 it was extended
to work for many more file types.

Bigger buffers will be allocated with mmap, with fallback to 4 kb
stack buffer if mmap fails.

help
Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
time intervals (time, ping, traceroute etc need this).
Probably requires Linux 2.6+. If not selected, gettimeofday
will be used instead (which gives wrong results if date/time
is reset).

saves about 1400 bytes.

config BUSYBOX_CONFIG_FEATURE_SKIP_ROOTFS
bool "Skip rootfs in mount table"
default BUSYBOX_DEFAULT_FEATURE_SKIP_ROOTFS
help
Ignore rootfs entry in mount table.
In Linux, kernel has a special filesystem, rootfs, which is initially
mounted on /. It contains initramfs data, if kernel is configured
to have one. Usually, another file system is mounted over / early
in boot process, and therefore most tools which manipulate
mount table, such as df, will skip rootfs entry.
However, some systems do not mount anything on /.
If you need to configure busybox for one of these systems,
you may find it useful to turn this option off to make df show
initramfs statistics.
Otherwise, choose Y.
