384aedab58 sh: Various warning fixes (from WARNS=6 NO_WERROR=1):
- const
- initializations to silence -Wuninitialized (it was safe anyway)
- remove nested extern declarations
- rename "index" locals to "idx"

2cac6e364a sh: Constify various strings.
Most of this is adding const keywords, but setvar() in var.c had to be
changed somewhat more.

55d2c5b573 Split updatepwd() into two smaller functions. The first one, findpwd(),
computes the new path and the second one, updatepwd(), updates the variables
PWD, OLDPWD and the path used for the pwd builtin according to the new
directory.  For a logical directory change, chdir() is now called between
those two functions, no longer causing wrong values to be stored in PWD etc. if
it fails.

ed5c24e27d Don't strip a leading ./ from the path for the cd builtin to avoid interpreting
.//dir as /dir.  Rather strip it only for the purpose of checking if the
directory path should be printed.

2ba1b30bf5 Changes following CScout analysis:
- Removed dead declarations
- Made objects that should have been declared as static, static.

The changes use STATIC instead of static, following the existing
convention in the rest of the code.

7e1975c2b2 Add a -P/-o physical option which behaves similarly to bash/ksh's options
by the same name. This option makes the cd and pwd builtins behave physically
(as opposed to logically) by default.

09086b0499 Bring back the cd -L and -P options from revision 1.24, but try harder not
to fail when the logical current directory no longer exists. Allow changes
to absolute paths when logical cwd is invalid, fall back to physical cd
if logical cd fails.

baf3e7c14b Temporarily back out revision 1.24; it seems to handle the case where the
current directory no longer exists incorrectly and breaks `make cleandir'.

f14c1c47f9 Don't call setvar() with the VTEXTFIXED flag. A copy is created by
setvar() and passed to setvareq(). When the VTEXTFIXED flag is set,
that copy is never freed, causing a memory leak.

avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

958ba632fa Make sh(1) a little braver in the face of adversity. sh(1)
now handles the getpwd() init problem the same way as bash
and ksh do.  Also while I was in here, I cleaned up the format
a little, removed some unnnecessary #if SYMLINKS cruft, and
changed the pwd builtin to use getcwd(3) as Joerg suggested.

aa9caaf657 Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault...  mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do.  The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..

beeac5cded Get this braindead, mongoloid shell look in /stand for pwd if it can't
find it in /bin.  This is something of a kludge, I know, but consider
my limited alternatives:  I can't make this an execvp() without making
people scream that I introduced a failure point or slowed down pwd,
and I can't make it an optional macro since crunch doesn't let you pass
arbitrary command-line args to the build of one of its crunch-ees.
This is the simplest, if not the nicest looking, solution I could come up
with.
