c98cbe25d2 31919: fix deadlock when a shell builtin with a multio redirection is used on the left side of a pipeline 
Make sure stdin/out/err file descriptors are closed for the multio copy
process, which means not re-using those descriptors after they are closed
and marked FDT_UNUSED in fdtable[].  For completeness, initialize their
fdtable[] state to FDT_EXTERNAL.

8c37e6f077 30272 (tweaked): most failures of fork() cause non-interactive shells to 
exit nonzero; bad options to "exec" cause exit under POSIX_BUILTINS.

Peter Stephenson
53f893d062 30181, plus rename of PF_* flags to PREFORK_*: 
Pass sh-wordsplitting instructions to paramsubst() using flags,
avoiding side effects of explicitly setting and unsetting the
SHWORDSPLIT option.

93139f39f1 30000 plus some comments: Better POSIXJOBs behaviour. 
Don't restore default SIGTTOU etc. behaviour if still doing job control.
Only carry on doing job control in subshell if it's a real
(...) subshell

92ee9324a9 29654: "wait" should resume stopped jobs identified by process ID as well 
as by job number; temporary (?) workaround for pipelines getting lost if
TSTP is delivered when a shell builtin is the tail of the pipe.
