[9] Review Request: 8176046 Replace package.html files with package-info.java in the java.desktop module

[Sergey Bylokhov]

Hello,
Please review the fix for jdk9. This is the last request which covers all 
packages in java.desktop(except javax.swing and java.awt which were covered 
earlier)
 - All "package.html" files were replaced by "package-info.java", even for 
internal packages like eawt.
 - All <tag> were replaced by {@tag }.
 - All files were manually reformatted - 80 chars per line.
 - <sup><font size="-2">TM</font></sup> was replaced by &trade; This is why the 
specdiff contains some diffs.
