RFR: 8207775: Better management of CipherCore buffers

[Anthony Scarpino]

If we are going to add more, here are two more ton consider:

- It looks like there is another Arrays.copyOf() on doFinal() line 851
- doFinal() at line 897 there might be something that should be done 
with 'buffer'.  In particular as a result of line 963's arraycopy().
