source code re-organization

[Erik Joelsson]

Great to see this getting ready! I'm trying it out in preparation for 
working on the build-infra-jigsaw build. Noticed a couple of things:

* Why the need to set MAKESHUFFLE_SRCDIR? I put the following in 
makeshufflescripts and it seems to work:
MS=$(cd "$(dirname "$0")" && pwd)

* In non-standard.includes, the line for jdwpTransport.h has an extra 
jdk/newsrc in the target path.

* zipfs.shuffle, zipfs.unshuffle and non-standard.includes contains 
target paths that look like "jdk/newsrc/$platform/module/...". I assume 
these should to be changed to mclasses and etc.
