b1526b43e8 Set the malloc alignment to 64 bytes on platforms that use the U-Boot API
device drivers.  Recent versions of u-boot run with the MMU enabled, and
require DMA-based I/O to be aligned to cache line boundaries.

These changes are based on a patch originally submitted by Juergen Weiss,
but I reworked them and thus any problems are purely my fault.

f497fbf5e4 - Removing some unneeded definitions of NULL(cruft related to 1970's C).
In C90, NULL is guaranteed to be declared in <stddef.h> and also in
  <string.h>.  Though the correct way to define NULL in FreeBSD is to
  include <sys/_null.h>, other parts of libstand still require <string.h>
  to build; therefore, we keep <string.h> in stand.h and add a note about
  this;
- Removing no longer used 'Prototype' definition.  Quote from bde@:

	'Cruft related to getting incomplete struct declarations within
	prototypes forward-declared before the structs.  It doesn't mean
	"prototype" but only part of a prototype-related hack.  No longer
	used.'

- Replacing iaddr_t with uintptr_t;
- Removing use of long double to determine alignment.  Use a fixed 16 byte
  alignment instead;

728fc2d633 Fixing building bustage on 32 bits platforms when WARNS >= 2. Note that
this fix only applies to zalloc.c, the other part of libstand such like
qdivrem.c still gives compilation warnings on sparc64 tinderbox builds;
therefore, WARNS level isn't changed for now.

7ab17e6d01 Just use uintptr_t and intptr_t rather than requiring each arch to provide
explicit int/long typedefs.

5a1c2d4f62 Trust the code more than the comment(s) and correct some false
statements about pointer data type sizes, which spread probably
by copy-and-paste.

21a7fd75c3 Reimplement malloc/free debugging that includes the offending file:line
info.  This turned out to be rather useful on ia64 for tracking down
malloc/free problems.
Detect duplicate free()'s - otherwise these show up as a guard1 failure
and it looks like corruption instead of something simple like a second
free() where there shouldn't be.
Deal with libz using libc headers and not seeing the malloc/free stuff that
we provide in libstand.  Do similar nastiness to what is done for bzlib.

Tested on: i386, ia64 (compile, run)

a2a9c8c79e Disable the end guard for now.
The test for failing the end guard was always triggering (and was reported as
such in compiler warnings).  This is a temporary band-aid until I can work
out what's really going on.

d58fb9293a To clarify last commit, msmith says:
The reason the Alpha has less room than the i386 is because the bootstrap
is given a 256K mapping by the firmware; to add more requires extra work.

95f5cf3349 Reduce the sbrk() increment from 64K to 4K. There's not much room on the
Alpha, and wasting potentially 64K-4 bytes of RAM just isn't an option.

* Fix a whole raft of warnings, printf and otherwise.
* Make zalloc work for alpha (just a case of using the right typedef).
* Add some (disabled) malloc debug printing to stand.h.

95b50c2be3 Replace the old and extremely icky Mach/NetBSD allocator with a similarly
compact and much better one donated by Matt Dillon.  Implement a simple
sbrk() which uses the existing setheap() api.

Remove the custom allocator from the UFS code.  It wasn't working quite
right, and it shouldn't be needed with the new allocator.

Fix a serious problem with changing the value of already-existent
environment variables.  Don't attempt to modify the supposedly-const
argument to putenv()

Fix an off-by-one sizing error in the zipfs code detected by the new
allocator.
