Detail:
  When splitting a free block in order to satisfy an allocation request,
    don't split if the remaining free space falls below a specified
    threshold (<= 8 bytes) to avoid creating lots of tiny free blocks,
    but instead gift the extra 8 bytes to the newly allocated block.
    This should stop the worst case heap fragmentation seen with OS_Heap
    heaps (particular the Toolbox's dynamic area).

  Tested in Ursula desktop build.


Version 5.44. Tagged as 'Kernel-5_44'

Detail:
  "Podule" number now displayed again in *ROMModule output - flag
     preservation issue caused it to disappear in 5.23.
  *Eval output no longer misses its trailing space, neither do "Podule" or
    "Extn ROM" in *ROMModules output.
  Heap manager now works again in non-SVC modes.
  Exception dump now contains faked up 26-bit PC+PSR lookalike.
Admin:
  Assembled.

Details:
  The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
  set to TRUE.
  If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
  although some internal changes have taken place to minimise compile
  switches between the two cases. See Docs.32bit for more technical info.

  The hardest part was the flood-fill...

Other changes:
  Pointer shape changes now take place on the next VSync, rather than actually
  WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
  down by 5% now :)

  Lots of really crusty pre-IOMD code removed.

Admin:
  Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
  will need to see a lot of use to iron out difficulties. I'd like anyone who
  has a non-frozen project to at least attempt using this Kernel.

Version 5.23. Tagged as 'Kernel-5_23'

* Integrated Ursula fast service call dispatch code.
* Added Interruptible32bitModes from Ursula.
* Stopped allowing ROM modules (other than the Kernel/UtilityModule) to write
  to the hardware vectors in 26-bit mode.
