RFR [9] Modular Source Code

[Mike Duigou]

There's a lot to review here. This is not a complete review but hopefully contributes to our review "coverage". I am focusing on the top project in this set of comments.

- --with-output-sync seems like it should be on by default if available. Downside? This could also be split out from the jigsaw changes if there is any interest in reducing the patch size.

- what is TESTMAKE_OUTPUTDIR for? (ugh, more outputdir dirs...)

- spec.gmk.in: Can we have a separate assignment for JAVA_TOOL_FLAGS_SMALL? It is nice to be able to see every AC_SUBST somewhere solo. 

- jdk-options.m4: should with_cacerts_file being empty not merit an error? what does the empty default do?

- javadoc.gmk: retire JDK_IMPSRC, JDK_GENSRC, JDK_SHARE_CLASSES and JDK_SHARE_SRC

- javadoc.gmk: JAVADOC_CMD should perhaps use (currently non-existant) JAVA_TOOL_FLAGS_BIG or at least JAVA_FLAGS_BIG?

- MakeHelpers: CleanComponent should call strip on the $1 argument to $(RM) so that it is deleting what it promises to be deleting. Or it could check to make sure $(words $1) is 1

- modules.xml "Changes to this file will require review by Committers to Project Jigsaw." Will this be true after integration into jdk9/dev repo?

- modules.list seems to be redundant with modules.xml but there don't seem to be any measures to ensure that they remain in sync. Even a comment in modules.xml would help. This kind of problem has been a source of errors in the past.

- What is TestMake.gmk and associated for?

jdk project:

- I am slightly unsettled by the number of makefiles and putting them all in to the same directory. Will they eventually be moved into their modules?

More to come but first I want to build it!

The new location of the source files can be determined from JEP 201 [1] and JEP 200 "The Modular JDK" [2], or by browsing the staging forest [3].
