ecb383966d sh: Constify internal representation in expand.c.
Forbid (temporary or permanent) modifications of the strings in NARG nodes
during expansion.

Tilde expansion now needs to copy the username for the terminating '\0'.

c917a39008 sh: Use OLDPWD shell variable for 'cd -'.
Per POSIX, 'cd -' should use the OLDPWD shell variable, not internal state.
This variable is normally exported.

Also, if OLDPWD is not set, fail 'cd -' instead of changing to the current
directory.

d42a26ab20 sh: Update associated state when restoring locals while leaving a function.
Some variables like PATH call a function when modified. Make sure to call
this also when leaving a function where such a variable was made local.

Make sure to restore local variables before shellparam, so getopts state is
not clobbered.

2d4b37e81d sh: Add a test for 'cd -'.
Redirect 'cd -' output to /dev/null since POSIX requires it to write the new

interactive.

68a5d0c372 sh: Ensure OPTIND=1 in subshell without forking does not affect outer env.
Command substitutions containing a single simple command and here-document
expansion are performed in a subshell environment, but may not fork. Any
modified state of the shell environment should be restored afterward.

The state that OPTIND=1 had been done was not saved and restored here.

Note that the other parts of shellparam need not be saved and restored,
since they are not modified in these situations (a fork is done before such
modifications).

b8cae6c53b sh: Remove redundant CTLQUOTEMARK checks.
With the new expand.c code, the intermediate representation passed to the
pathname generation code only contains CTLESC, not CTLQUOTEMARK.

CTLQUOTEMARK now only occurs in the text of NARG nodes (output of the
parser).

e4f897d527 sh: Perform pathname generation during the first expansion phases.
This avoids the need to add and remove CTLESC bytes if pathname generation
will not be performed (set -f).

Side effect: the order of operations is slightly different: pathname
generation in ${$+* $(CMD)} will not see filesystem changes from CMD.

098890d688 sh: Perform IFS splitting during the first expansion phases.
This simplifies the code and should be faster in some cases.

Side effect: the order of operations is different so that the value of IFS
used when IFS is modified during expansion (${IFS:=...}, ${IFS=...} or
$((...IFS=...))) may be different. Note that this order is highly unportable
between shells.

4ede56bd51 Fix ls -l alignement with new locales
Latest update of locales introduced abbreviated month that follows the regionale
rules meaning that they can be of variable length instead of being arbitrary
truncated to top 3 characters.

To fix alignement, ls now computes the visible length of the abbreviated month,
pads the shorter month with spaces in order to make sure everything is properly
aligned

44973a75bb Update dependencies after r291406 added libelf to libkvm.
Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm.  Churn would be
reduced if this was able to be limited to direct dependencies.

52255645fb META MODE: Don't create .meta files when symlinking sources into the obj directory.
Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file.  There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

5edc3be36a sh: Make struct arglist an array instead of a linked list.
This simplifies the code (e.g. allowing use of qsort(3) instead of a
hand-rolled mergesort) and should have better cache properties.

The waste of unused args arrays after resizes is approximately the same as
the savings from getting rid of the next pointers.

At the same time, remove a piece of global state and move some duplicated
code into a function.
