[Classpathx-crypto] latest checkin

[Raif S. Naffah]

i checked in this afternoon an implementation of David McGrew's TMMH/16 
(version 1) -gnu.crypto.mac.TMMH16- as well as a test case for it 
-test.mac.TestOfTMMH16.  this is in preparation for the implementation 
of the UST (Universal Security Transform).

the count of tests is now up to 93!  i.e. if you run:

ant test

you should see at the end:

[junit] OK (93 tests)


other classes were also amended to allow instantiation for this new 
algorithm.

i also implemented Cloneability for the PRNG implementations we already 
have.


cheers;
