85bed93092 Rationalise use of forks and pipes. 
Ensure we _exit instead of returning from execcmd_exec() if we
have forked.  Before the optimisation code after the fork always ran
to the check at the end, but that code is overkill for the logic
between the early fork and the existing one.

Remove old workaround to fork in caller of execcmd for current shell
constructs as no longer needed with early fork below.

Close input of newly created pipe on fork (destined for RHS of pipe
which we never execute): this replaces a workaround from
zsh-workers/32171, commit 9887fc3d7b.

Set last1 on early fork as needed by some instances of shell
constructs on LHS of pipeline to know they are exiting.

cbe1c8eff5 Make early fork even earlier. 
It was after our preliminary scan of arguments to find
a command.  Actually, in the cases of early fork
we don't need this information before forking.

0d33815047 42693: Fork early for pipelines. 
If executing a command not at the end of a pipeline, and
not optimised in the calling code, we can fork before
"prefork" substitutions, at the same point as
for background commands.

9e2afb9298 42684 (with extra comments): Fork early if in bg. 
In execcmd the case of running the last command in a pipeline
asynchronously for the purpose of & and &! is easy to work out,
and we can avoid side effects and unnecessary execution time in
the parent shell by forking earlier.

0f29b5148e 42686: Fix previous pgrp patch. 
We shouldn't do any fix ups unless the process has actually
exited.

3c74891fcd 42630: Improve process group handling in pipelines. 
If process group leader exits, allow a newly forked process to become
process leader.  If a foreground job, reattach the shell to the
terminal until that happens.

Unblock signals when reading output for command subsitution so that
we can do this reattaching immediately.
