awk: Syntax error if delete isn't given an arg.
...
Unlike exit and return, delete strictly requires an arg, and derefs a
null pointer if executed without one.

awk: Guard pointer chasing when parsing ternary expressions.

Avoids an uninit pointer deref for some malformed ternary exprs.

start-stop-daemon: create pidfile before parent exits, closes 8596
...
This removes DAEMON_DOUBLE_FORK flag from bb_daemonize_or_rexec(),
as SSD was the only user.
Also includes fix for -S: now works without -a and -x,
does not print pids
(compat with "start-stop-daemon (OpenRC) 0.34.11 (Gentoo Linux)").

bc: remove "error after expression parsing" check
...
It is misplaced: caller knows better what can or cannot follow the expression.
Sometimes even caller's caller: "if (1) return a+b else..." -
parser of "return" does not know that "else" after it is valid,
parser of stmt does not know it either, - only parser of
"if" knows it!
The removed code balked on e.g. "{ print 1 }" statement.
This does not break any valid programs, but starts accepting some
invalid ones, e.g. "print 1 print 2" would work.

bc: partially rewrite parser, tests pass, ^C might be broken now
...
The entire control construct (if/while/for/funcdef) or {} block is
"eaten" by the corresponding parsing function, instead of maintaining
special "block flag stack" with magic bits in it, and returning to main
input loop after every inner statement (every input line, essentially).
This required moving line input deep into lexer - now zbc_lex_next()
triggers more reading when needed.
"block flag stack" is gone.
Correctness of ^C handling wasn't checked, might need fixing now.
if/else syntax is changed to match GNU bc: "else" can not be on
the next line (the rationale is that "if (1) 2" statement in interactive
mode should execute and print 2 instead of waiting for possible
"else ..." line).
This change fixes the following examples:
if (1) if (1) 1 else 2 else 3
if (0) 1 else if (1) 2
define w() { auto z; return 1; }

tar,unzip: postpone creation of symlinks with "suspicious" targets
...
This mostly reverts commit bc9bbeb2b8https://bugs.busybox.net/show_bug.cgi?id=8411
In particular, this interferes with unpacking of busybox-based
filesystems with links like "sbin/applet" -> "../bin/busybox".
The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag -
it is unused since 2010, and removing conditionals on it
allows commonalizing some error message codes.

od_bloaty: fix floating point output
...
Currently od_bloaty does this:
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -f
od: invalid character 'F' in type string 'fF'
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t fD
od: invalid character 'D' in type string 'fD'
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t f
0000000
0000010
The first two occur because the alphabetic length specifier isn't being
properly skipped. The third is due to the empty length specifier being
treated as alphabetic so we fall off the end of the FDL_sizeof array with
undetermined consequences. Coreutils defaults to printing a double in
this case.
With this patch the output is:
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -f
0000000 0.0000000e+00 0.0000000e+00
0000010
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t fD
0000000 0.000000000000000e+00
0000010
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t f
0000000 0.000000000000000e+00
0000010
I guess nobody uses BusyBox od to print floating point numbers.
