Add second ctor to StreamTransformationFilter for authenticated encryption modes
...
StreamTransformationFilter had a small hack to accomodate AuthenticatedEncryptionFilter and AuthenticatedDecryptionFilter. The hack was enough to support CCM, EAX and GCM modes, which looks a lot like a regular stream cipher from the filter framework point of view.
OCB is slightly different. To the filter framework it looks like a block cipher with an unusual last block size and padding scheme. OCB uses MandatoryBlockSize() == BlockSize() and MinLastBlockSize() == 1 with custom padding of the last block (see the handling of P_* and A_* in the RFC). The unusual config causes the original StreamTransformationFilter assert to fire even though OCB is in a normal configuration.
For the time being, we are trying to retain the assert becuase it is a useful diagnostic. Its possible another authenticated encryption mode, like AEZ or NORX, will cause the assert to incorrectly fire (yet again). We will cross that bridge when we come to it.

Revert AltiVec and Power8 commits
...
The strategy of "cleanup under-aligned buffers" is not scaling well. Corner cases are still turing up. The library has some corner-case breaks, like old 32-bit Intels. And it still has not solved the AltiVec and Power8 alignment problems.
For now we are backing out the changes and investigating other strategies
