There's no direct change in PPP_ContentDecryptor_Private interface, but
PPP_ContentDecryptor_Private interface uses PP_EncryptedBlockInfo which has been
changed. So I think we should still bump the label here. Is this correct?

I'm not that familiar with content decryption, but if plugins that use it aren't
released in sync with Chrome, then you need to keep the old version and support
the older struct. See my comment on PP_EncryptedBlockInfo.

See above.
