Notification upon completion of compilation

[Jonathan Gibbons]

FWIW, the com.sun.source.* API is a supported API, albeit a JDK API and 
not a Java SE API.

Tracking started/ended events seems like a reasonable way to infer when 
compilation is complete, but note that after parsing all the files on 
the command line at the beginning of the compilation, javac may read 
additional files later on, while analyzing files that have been read. 
These additional files are those that javac needs to implicitly compile 
in order to complete the compilation of the files given on the command line.
