Moved all rust code into src

[farcaller]

That is, ioreg, platformtree and macro code.

[bharrisau]

Fast builds!

[farcaller]

Yup, I looked at that 6sec build and actually went to ci.zinc.rs to verify that there was some building involved :-)

[farcaller]

r anyone?

[farcaller]

actually not anyone but specifically @bharrisau (due to crago work) and @bgamari (due to ioreg crate moves)

[bgamari]

Looks good to me. I'll let @bharrisau give the r

[bharrisau]

LGTM - Is there a reason we need the ioreg crate separate from the ioreg macro/plugin_registrar definition?

[bgamari]

@bharrisau I did this modelling the platformtree code.

[farcaller]

I've tried unifying macro_ioreg and macro_platformtree into one crate but than I've realised that ioreg is a zinc dependency and pt is end user code dependency, so there's little sense it that

[bharrisau]

@farcaller I meant having the platformtree crate separate from the
platformtree plugin registrar.

[farcaller]

Uh.. I don't really know :-) might merge those two actually.
