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. Submitted by: zmalloc from Matt Dillon <dillon@backplane.com>
