Code review: Allow protoc to output directly to zip/jar.

[Kenton Varda]

Hi Ambrose,

When you have a chance, can you please review this change:

  http://code.google.com/p/protobuf/source/detail?r=282

The effect is that protoc can output directly to zip files (and it recognizes jar, war, and par as being aliases for zip):

  protoc --java_out=foo.jar foo.proto

BTW, we should probably attribute the source of the CRC table.  Where did you get it?

(Please note that I've CC'd the public mailing list on this e-mail.)

This would be so much more awesome if javac could take source jar files as input and simply compile everything in the jar.  But no.  Hmph.  I guess I will need a stupid wrapper script.
