Use signed char cast to avoid out-of-range error on PowerPC (which has

unsigned char by default). This is a no-op on all other current arches. Tested by: md5 sum before/after same on i386

numbers aren't pointers. - Add a __printflike() attribute to libstand's panic() prototype to catch such bogons in the future.

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)

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
