Revert "Revert "Cut down on object allocation in CipherInputStream""

As Cipher#getOutputSize can return different value in some cases for the
same cipher object and input buffer.
To accomodate the behavior, the size of the output buffer should be checked
every time when the CipherInputStream#getMoreData is called and whenever
the new size is greater than the current size, array must be reinitialized.

This reverts commit 298b528c.
