expbackq() was incorrectly backing up a temporary buffer when removing \n
...
from the end of output of commands inside $(...) substitutions.
If the program output is n*128+1 bytes long (ending in a \n) then the code
checks buf[-1] for another \n - looking an uninitialised stack.
On a big-endian system an integer of value 10 will satisfy this (unlikely
on little endian) and can happen depending on the last code path to use
a lot of stack!
This caused the problem with newvers.sh on sparc64 after ', 2005' was
added to the date list.

- 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...)

Revert previous change. No need to save rootshell. It is only affecting
...
the non-vfork case. Having said that, it would be nice if pipelines of
simple commands were vforked too. Right now they are not.
Explain that setpgid() might fail because we are doing it both in the
parent and the child case, because we don't know which one will come
first.
Suspending a pipeline prints %1 Suspended n times where n is the number
of processes, but that was there before. It is easy to fix, but I'll
leave the code alone for now.
