When include/applets.h is re-generated
it generates code macros in include/applets.h e.g.
IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat))
...
IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt))
...
sed is used to process source files like below to feed into this header
generation
sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c
this means we let shell decide the order of .c files being fed into sed
tool, applets.h has code snippets thats generated out of code fragments
from these .c files and the order of the generated code depends on the
order of .c files being fed to sed and then piped to generate tool, even
though the generated code is logically same, it does result in re-odered
code in applets.h based on which shell was used during build on exact busybox
sources since sort order is different based on chosen locale and also default shell
being bash or dash
This sets the environment variable LC_ALL to the value C, which will
enforce bytewise sorting, irrespective of the shell

"-x vendor:VENDOR" will not be a trivial replacement of it:
(1) by default, we do send a vendor string ("udhcp BB_VER"),
will need code to preserve the default.
(2) -V '' currently disables vendor string. -x vendor:''
would not easily achieve that: it adds no option at all
(string options can't be empty), and default (1) would trigger.
To avoid that, we will need yet another hack to detect
-x vendor:'' and interpret that as "no vendor string at all".
IOW: removing -V is likely to increase code size, not decrease.

While at it, rename bb_signals_recursive_norestart() to bb_signals_norestart():
"recursive" was implying we are setting SA_NODEFER allowing signal handler

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.

Even following current Internet standards, it can be perfectly
legitimate to issue IPv4 addresses that end in .0 or .255 via DHCP --
this can happen whenever the network is larger than /8. For example,
10.3.4.0 and 10.3.4.255 are legitimate host addresses in 10/8 or 10.3/16.
(We also want to be able to issue .0 addresses in smaller networks
following our proposed kernel patch and standards changes.)
This behavior is already fully controllable by the user, simply by
setting start_ip and end_ip correctly. Users who don't want to issue
.0 or .255 should set start_ip greater than .0 or end_ip less than .255
and udhcpd will already respect these bounds. (This is also the case
for other DHCP servers -- the recommended example configurations will
default to a lower bound starting with .1 or some other value, which is
typically appropriate, but the user is still allowed to change this to
.0 -- or to a range that overlaps a .0 or .255 address -- if so desired.)

This restores old behavior where we slept for 1/2 of lease, then tried renewing,
thel slept for 1/4 and tried again, etc. But now we will NOT be listening to
all packets for 1/2 of lease time, processing (rejecting) everyone else's
DHCP traffic.
We'll go back to bound state, where we have no listening socket at all.

Lines that have no content apart from automatic indentation should
be treated as empty when the user hits return or ESC.
The implementation uses the global variable 'indentcol'. Usually
this is zero. It can also be -1 to indicate an 'O' (open above)
command, replacing the overloading of the tabstop option bit.
A value greater than zero indicates that the current line has
been autoindented to the given column (or that the autoindent has
been adjusted with ctrl-D). Any other change to the line resets
'indentcol' to zero.
Replace strspn() with ident_len(). The latter handles the unlikely
case that it's called on the last line of a file which doesn't have
a terminating newline.

Autoindent took a copy of the indent from a neighbouring line, which
may not have respected the expandtab setting.
Determine the target column and construct a suitable indent. This

Commit 24effc7a3 (vi: cursor positioning after whole-line 'y')
tried to save a few bytes by treating whole-line deletion the
same as whole-line yank. If the deletion removed the last lines
of the file the cursor was left beyond the end of the file.
Revert the part of the commit related to whole-line deletion.
Position the cursor on the first non-whitespace character of the
line when whole lines are 'put'.

The 'y' command to yank text should leave the cursor at the start
of the range. This mostly works correctly in BusyBox vi but not
for whole-line yanks with backward motion, e.g. '2yk' to yank two
lines backwards. In this case the cursor is left at the end of the
range.
Fix this by returning the actual range from find_range(). Cursor
positioning following whole-line deletion is inconsistent between
vim and traditional vi. For BusyBox vi chose the option that uses
least code without being exactly compatible with either.
Also, find_range() preserved the value of 'dot', the current cursor
position. Since this isn't used by either caller of find_range()
we can save a few bytes by not bothering.

This allows to fix a problem that we wait for renew replies
for up to half the lease (!!!) if they never come.
Make it so that lease of 60 seconds is not "rounded up" to 120 seconds -
set lower "sanity limit" to 30 seconds.
After 3 failed renew attempts, switch to rebind.
After this change, we can have more flexible choice of when to do
the first renew - does not need to be equal to lease / 2.

Commit 7a8ceb4eb (vi: changes to line addresses for colon commands)
was supposed to address the issue:
When the last address is empty it should refer to the current line.
This was intended to allow ranges of the form '1,' with an empty
last address. It should have been expressed as:
When the last address is empty *and the second last isn't* it
should refer to the current line.
Otherwise a command like ':w' only writes the current line resulting
in serious loss of data.
