1c42c18e96 awk: Fix overly permissive func arg list parsing 
It allows things like 'func f(a b)' and 'func f(a,)' which GNU awk forbids.

08a514c097 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.

dac15a10ac awk: Guard pointer chasing when parsing ternary expressions. 
Avoids an uninit pointer deref for some malformed ternary exprs.

Add a test that would crash in busybox before this fix.

088fec36fe 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)").

ce51140664 passwd: initialize pointers correctly 
Fix for running passwd as root (or sudo passwd $USER).
Crashed on call to free(orig) during cleanup.

Fix regression from commit 17058a06c4
Root user never changes the orig pointer, so when cleaning up, passwd tried to
free orig=(char*)""
Example: sudo passwd $USER
Changing password for xxx
New password:
Bad password: too short
Retype password:
Passwords don't match
free(): invalid pointer
Aborted
