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.

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.

* Embedded platforms using the u-boot API drivers require that all I/O buffers
* be on a cache line sized boundary. The worst case size for that is 64 bytes.
* For other platforms, 16 bytes works fine. The alignment also must be at
* least sizeof(struct MemNode); this is asserted in zalloc.c.
