Back out a dubious Lite2 change to "optimise" getcwd() to look at $PWD
because it's potentially dangerous (think: symlink races). Move
realpath() back to it's original location, and remove getcwd_physical()
by renaming it back to getcwd() and zapping the original getcwd wrapper.

This will make a number of things easier in the future, as well as (finally!)
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.
Add progname to warning/error message layout. (joerg)
Remove inline assembler, no speed impact, not need for the obfuscation (bde)
Remove on the fly calculation of parameters, no longer critical.
Make D & U flags valid even if we don't support them.
Don't call imalloc until we're done initializing.
Zap contents on free() if we have "Junk" set. [*]
Various nitpicking.
[*] As a sideeffect of this change, if you are worried about
sensitive data lingering in memory, you can use the 'Junk' option
now to make sure phkmalloc zaps memory when it is returned. add
char * malloc_options = "J";
to your source. Obviously there is a performance impact.
Various neat features added. More documentation in the manpage.
If your machine has very little RAM, I guess that would be < 16M
these days :-(, you may want to try this:
ln -fs 'H<' /etc/malloc.conf
check the manpage.
as done after a quasi-recursive call to free() had modified what we
thought we knew about the last chunk of pages.
This bug manifested itself when I did a "make obj" from src/usr.sbin/lpr,
then make would coredump in the lpd directory.
in a bunch of man pages.
Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
by W.Richard Ste vens. EINTR handling suggested by bde@freebsd.org).
Code cleanup:
1. Add missing return type.
2. Replace 'union wait' by int.
3. Use Posix-style signal handling instead of signal().
4. Use fork() instead of deprecated vfork().
5. Block signals before fork()'ing, instead of after.
6. Return -1 if fork() fails, instead of 0.
7. Add EINTR handling for waitpid() call.
Also add claim of Posix conformance to man page.
in the main text of various man pages.
Thanks to Warner Losh for adding an option to manck to allow
it to scan the entire man page looking for bogus xrefs, instead
of just checking the SEE ALSO section.
