Initial webrev with changes for JDK 9

[Bhavesh Patel]

Hi,
     I have review the javadoc (including doclet and tests) changes. It 
mostly looks good. Following are my comments on the changes

1) jdk/javadoc/internal/doclets/formats/html/ConfigurationImpl.java

- (Line 522) PackageSymbol "pd" is cast to ModuleSymbol which is incorrect.

2) jdk/javadoc/internal/doclets/toolkit/AbstractDoclet.java

- (Lines 109 and 111) e.printStackTrace() needs to be deleted.

3) jdk/javadoc/internal/doclets/formats/html/PackageWriterImpl.java

- (Lines 130 - 135) The Module label and name gets enclosed in <p>. We 
need to update this to enclose them in a <div> and <span> similar to 
what we do in 
jdk/javadoc/internal/doclets/formats/html/ClassWriterImpl.java (Lines 
200 - 205).

Other minor changes that are needed are as follows

4) com/sun/tools/doclets/formats/html/PackageWriterImpl.java

- The class lists no changes other than the copyright year change. If no 
changes have happened, the copyright year change needs to be reverted.

5) com/sun/tools/doclets/internal/toolkit/taglets/TagletManager.java

- (Line 275) Missing @param.

10) jdk/javadoc/internal/doclets/toolkit/Configuration.java
