Build support for JDK-8044627

[Erik Joelsson]

Hello,

The main problem is that we now will have Gensrc-$m.gmk for the same 
module in multiple repos. Now, that just happened again with my patch to 
split GensrcProperties.gmk (jdk.dev has gensrc in both langtools and 
jdk), so I took the time to solve it in M2. What I mean by this is that 
M2 is prepared to handle it and the merge will not be that complicated 
anymore. I would rather have it done and dealt with early.

If you like lets defer addressing the general problem of concatenating service configuration files until jigsaw/m2 is in the JDK 9 mainline. There is no urgency on this, and no point adding unnecessary merge complication ( which I think it what you are suggesting ).

There is an extra complication at the top level as java.corba already had a gensrc step in the corba repo. The proper solution for that part will have to be done in Jigsaw M2, the merge will be hairy. I also had come up with a way to only include one of the files in resources.jar, since the jar command doesn't like duplicate entries. This is a bit of a hack, explicitly excluding 3 of the files, but since resource.jar is going away in M2 anyway, I think it's fine for now.

My guess is that 'META-INF/service/javax.naming.spi.InitialContextFactory' files from different modules are being copied into the same jar. What I really need to have is a single concatenated 'META-INF/service/javax.naming.spi.InitialContextFactory' file with 4 lines. It will work fine for now.
