enami 87aaf3d70d Fix a bug introduced by previous commit. It breaks export command
with multiple arguments if one of them are already set.  Fix PR#27155
and probably PR#27143.

dsl 5f9b910124 Save the length of each variable in the name table so that we can
compare the lengths and then use memcmp() in the search code.
Speeds up one of my scripts by a facter of 2.
Increase the size of the variable hash table.
Cuts down time for script to execute from 60 seconds to 10.
Move variable search into a new function to hide the implementation
from most of the code, new version is slightly smaller than old.

christos c02b3bbdf4 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...)

christos edcb454443 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.

cgd 84d782a52f __CONCAT does token pasting, not string concatnation. if something like:
__CONCAT("PATH=",_PATH_STDPATH);
actually works to concantate strings, it's because the preprocessor expands
it into "PATH=""whatever _PATH_STDPATH is" as separate strings, and then
ANSI string concatenation is performed on that.  It's more straightforward
to just use ANSI string concatenation directly, and newer GCCs complain
(rightly) about mis-use of token pasting.

fair 618cca243b Change a few things to reference /usr/include/paths.h instead of local
references. Fixing the default PATH is a bit more effort.
