Review request for 6414899 and 7058133

[Valerie (Yu-Ching) Peng]

Vinnie,

Can you please review the fixes for the following bugs?

6414899 "P11Digest should support cloning"
7058133 "Javah should use the freshly built classes instead of those 
from the BOOTDIR jdk"

Well, the Solaris implementation for message digest cloning is quite 
buggy, so I left the message digest mechanisms disabled.

Thanks,
Valerie
