RFR: JDK-8234078: Missing license headers in a few javac files

[Jan Lahoda]

Hi,

There is a handful of javac-related files with missing license headers 
or license headers with typos:
-make/langtools/tools/propertiesparser/resources/templates.properties
the proposal is to add the license header
-src/java.compiler/share/classes/javax/lang/model/util/AbstractElementVisitor7.java
typo in the license header
-src/jdk.compiler/share/classes/META-INF/services/com.sun.tools.javac.platform.PlatformProvider
src/jdk.compiler/share/classes/com/sun/tools/javac/services/javax.tools.JavaCompilerTool

These appear unnecessary (their functionality has been moved to 
module-info, I believe), so the proposal is to remove them.

Proposed patch:
http://cr.openjdk.java.net/~jlahoda/8234078/webrev.00/index.html

JBS: https://bugs.openjdk.java.net/browse/JDK-8234078

How does this look?

Thanks,
     Jan
