[8u] Request for approval for CR 8176329 - jdeps to detect MR jar file and output a warning

[Brent Christian]

Hi,

I am requesting approval to push my changes for 8176329 - "jdeps to 
detect MR jar file and output a warning".

Bug:
https://bugs.openjdk.java.net/browse/JDK-8176329

Webrev:
http://cr.openjdk.java.net/~bchristi/8176329/webrev.05/

Review thread:
http://mail.openjdk.java.net/pipermail/jdk8u-dev/2017-April/006602.html

Along with the new MR jar warning message, the change also updates 
messages for the "-jdkinternals" option, as suggested by Mandy in the 
bug report.

Thanks,
-Brent
