Done as the above, an added bonus is we no longer have to SvREF_dec()
so its even simpler.

I clearly needed more caffeine in my system when i wrote that. Partly
due to the shadowed "av" variable. I've fixed it by initiating all of
the dims to 0. I also renamed the shadowed av var to "nav" for nested
av.

So the merge while not exactly trivial was fairly simple. However it
would be great if you could give it another look over.

Find attached v7 changes include:
- rebased against HEAD
- fix potential use of uninitialized dims[cur_depth]
- took out accidental (broken) hack to try and support composite types
in ::encode_array_literal (added in v4 or something)
- make_array_ref() now uses plperl_hash_from_datum() for composite
types instead of its own hand rolled version
- get_perl_array_ref() now grabs the 'array' directly instead of
through the magic interface for simplicity
- moved added static declarations to the "bottom" instead of being
half on top and half on bottom
