Version 5.35, 4.79.2.48. Tagged as 'Kernel-5_35-4_79_2_48'

Ursula. Quite a hairy code merge really, so let's hope it is
worth it to someone. What you get (back after 2 or 3 years):
- much more efficient for largish numbers of DAs (relevance
  to current build = approx 0)
- fancy reason codes to support fast update of
  Switcher bar display (relevance = 0)
- support for clamped maximum area sizes, to avoid address
  space exhaustion with big memory (relevance = 0)
- better implementation of shrinkable DAs, performance
  wise (if lots of DAs, relevance = approx 0)
- support for 'Sparse' DAs. Holey dynamic areas, Batman!
  (relevance, go on someone use the darned things)
Moderately development tested on HAL/32bit ARM9 desktop.
Note the Switcher should be compiled to use the new
reason codes 6&7, for fabled desktop builds.

Also, during this work, so I could see the wood for the
trees, redid some source code clean up, removing pre-Medusa
stuff (like I did about 3 years ago on Ursula, sigh). That's
why loads of source files have changed. The new DA stuff
is confined pretty much to hdr.KernelWS and s.ChangeDyn.

Ta.

Version 5.35, 4.79.2.38. Tagged as 'Kernel-5_35-4_79_2_38'

First attempt at ARM9 support, and general clean-up of old ARM-specific code, now using vectored ARMops.

Not tested.

Version 5.35, 4.79.2.14. Tagged as 'Kernel-5_35-4_79_2_14'

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.

Not fully tested on all hardware permutations.
