1df0cb4093 as a more general solution to fd leak detection, just do CLOEXEC manually 
(this also allows us to see “real” leaks)

12c662b6e2 thanks to ISC (Interactive) Unix, we now know a few samples of errnos 
that get used, plus one for the realpath-1 regression test; also make
sys_siglist_decl detection nicer and poison strerror() with non-const
return value ifdef DEBUG, make it always const

77c4cb88e4 implement tty tracking and bump to R41 for feature completeness 
• tty_fd is now never closed
• new tty_hasstate tracks tty_state (cf. thread around
  http://article.gmane.org/gmane.os.miros.mksh/79 and PLD bug)
• as users requested, importing COLUMNS or LINES from the environment
  now removes its special-ness as does unsetting it
• otherwise, setting COLUMNS or LINES is honoured until the next SIGWINCH
  arrives or change_winsz is otherwise run (e.g. before displaying the
  prompt in the interactive command line editing modes)
• SIGWINCH is now honoured before each reading of $COLUMNS and $LINES too
• change the Uhr to match – it no longer calls stty(1) ☺

31f24a4040 add some bounds, for a subsequent commit: 
• all writers of exstat ensure the value is in [0; 0xFF]
• all readers of exstat AND it with 0xFF (not strictly needed thus)
• trap_exstat is “safe”, i.e. always either -1 or [0; 0xFF]

bebb2d2254 EXPERIMENTAL optimisation for “sh -c 'foo'” to equal “sh -c 'exit foo'” iff 
several conditions are met as outlined below; for more background, refer to
http://www.FreeBSD.org/cgi/query-pr.cgi?pr=113860

We don’t yet optimise 「% sh -c '{ echo a; sleep 10;}&'; sleep 1; ps T」 so
the FreeBSD® sh approach cannot work for us, but scanning the “sh -c” argu‐
ment for disallowed characters and, if not, setting a flag that enables the
shell to exec the tree when parsed as TCOM *and not c_trap()* was possible.

Disallowed characters are currently C_QUOTE except space, that is:
Tab Newline " # $ & ' ( ) * ; < = > ? [ \ ] ` |

This should catch all cases of magic, variables, subshells, pipelines, etc.

9fbdef8e60 pure RCSID sync with OpenBSD, as we introduced SIGWINCH tracking earlier 
XXX we could track whether tty_fd has already been successfully opened,
XXX the ttystate initialised, and then just never close it unless it is
XXX necessary, then we can keep COLUMNS/LINES accurate in scripts, even

95a2c63096 • implement fcntl(2)-based advisory locking as an alternative iff flock(2) 
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
  documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all
