Summary
-------

Add `-proc:full` to explicitly specify both annotation processing and compilation are requested of `javac`. (This is currently the default policy.) No changes from original CSR JDK-8308346.

Problem
-------

The default policy for annotation processing does not have a value for the `-proc` option.

Solution
--------

Add `-proc:full` as a third recognized option, alongside `-proc:none` and `-proc:only`.

Specification
-------------

The `-help` output of `javac` will mention the new alternative:

      -proc:{none,only,full}
            Control whether annotation processing and/or compilation is done.

and the `javac` "manpage" will be updated similar to:

    -`-proc:`\[`none`, `only`\]
    +`-proc:`\[`none`, `only`, `full`\]
     :   Controls whether annotation processing and compilation are done.
         `-proc:none` means that compilation takes place without annotation
         processing. `-proc:only` means that only annotation processing is done,
    -    without any subsequent compilation.
    +    without any subsequent compilation. `-proc:full` means that annotation
    +    processing is done with subsequent compilation.
