hg: build-infra/jdk8/jdk: 70 new changesets

[Alan Bateman]

Erik,

Looks like good progress has been made on converting the old make files.

One question (and I brought this up on another thread but didn't get a 
reply) is where is jdk/makefiles going. Personally I find it surprising 
to see the Gensrc*.gmk files for various random areas of the JDK is one 
directory. Same thing with CompileNativeLibraries.gmk and 
CompileJavaClasses.gmk where compilation for libraries from various 
areas of the JDK have their exceptions dealt with in the same make file. 
So I guess I'm just trying to understand what the conventions will be as 
there are some per-package/area directories in the new makefiles tree too.

-Alan.
