296f8c148a Add a missing THREAD_UNLOCK() found missing by Valentin Nechayev
<netch@segfault.kiev.ua>

Remove allocation failure check from 'A' option, the 'X' option does
this as a standalone check now.

30af2ca344 Add history: The reallocf() function first appeared in FreeBSD-3.0.
See imp's 199808201619.KAA20970@harmony.village.org in freebsd-hackers (the
reallocf.c cvs history mistakenly refers to freebsd-current).

eed7c97f34 Disable the "Hint" option in phkmalloc as default. Recent VM system
changes have made this too expensive.  This gains about 1.25% on
worldstone on my SMP machine.

Swap-less machines, for instance PicoBSDs, and machines which experience
page-out trafic, check with top(1), will probably want to reenable this
with:
	ln -s H /etc/malloc.conf

d54a12dd1f Add reallocf to the library. This function is simliar to realloc, but
when it returns NULL to indicate failure, it will also free the memory
that was passed to it, if that was non-null.

This does not change the semantics of realloc.

A second commit will be done to commit the conversion of those places in
the code that can safely use this to avoid memory leaks when confronted
with low memory situations.

a4c2098502 malloc_sysv used before initialized, reported in PR4002 by
Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru>

Various cleanup from Keith Bostic

Reinstate calloc() as a separate funtion, in its own source/object file.
leave the manpage integrated with malloc.3 and friends.  Too many things
were broken in this respect.

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

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.

"zero' and 'junk' options to help find and diagnose malloc abuse.
EXTRA_SANITY defaults "junk" to on.
Don't dump the internal state, unless EXTRA_SANITY.
General code cleanup.
Error messages cleaned up a bit, more checking earlier.
EXTRA_SANITY is default at this time (just in case).
Performance (without EXTRA_SANITY) is better, beats gnumalloc in
both time & space most of the time:

3f27b3de03 ``phkmalloc''
Performance is comparable to gnumalloc if you have sufficient RAM, and
it screams around it if you don't.
Compiled with "EXTRA_SANITY" until further notice.
see malloc.3 for more details.
