malloc_pages should be static.

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.

Fix a typo.

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.
