Wrap declaration of a STATIC function that's only conditionally defined
...
in a suitable ifdef, so things still compile if STATIC is defined as
"static", which is for some reason not the default.
(In the long run STATIC should go away - it might have once been a
portability hack but now definitely serves no purpose.)

Fix bin/20185 - builtin called from function of same name mustn't be hashed.

non-posix 'hash -v' will report everything.

Fixes from David Laight:
...
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
(so I could unset -e PS1 before running the test shell...)

VFork()ing shell: From elric@netbsd.org:
...
Plus my changes:
- walking process group fix in foregrounding a job.
- reset of process group in parent shell if interrupted before the wait.
- move INTON lower in the dowait so that the job structure is
consistent.
- error check all setpgid(), tcsetpgrp() calls.
- eliminate unneeded strpgid() call.
- check that we don't belong in the process group before we try to
set it.
