Changes in sb-heapdump-05
  * x86-64 fixes
  * PowerPC/cheneygc port
  * alien fixups

Changes in sb-heapdump-04
  * s/:supersede/:rename-and-delete/, because SBCL does not, as the spec
    says, create a *new* file under the old name, but rather overwrites
    the data in the old file using O_TRUNC!  Not a good idea when the
    file in question is currently mapped into dynamic space!
  * convenience function DUMP-SYSTEM for ASDF systems
  * MAKE-EXECUTABLE hack
  * allow .heap files to be concatenated
  * don't duplicate SB-IMPL::*PHYSICAL-HOST*

Changes in sb-heapdump-03
  * support for SAPs
  * support for weak pointers
  * avoid recomputing gf dfuns multiple times
  * mark hash tables for rehashing if a hash value is eq-based
  * keep an explicit worklist to avoid overflowing the stack for deep graphs
  * fixed CTORs (ensure-ctor sometimes returns NIL...)
  * user fixups; removed :PARAMETERS in favour of :CUSTOMIZER
  * new howto: climacs
  * relocate heap files manually instead of relying on GC, eliminating
    the need for a patch to SBCL and allowing files to be mapped without
    any relocation if the targeted space is free.
