[GNU Crypto] Ent bug, Version 2.0.1

[Karsten Tinnefeld <karsten@xxxxxxxxxxxxx>]

Dear gnu-crypto-developers:

the Ent tool to determine basic statistical parameters of an RNG seems 
to have a little effect: once it examines the distribution of a 
generator which delivers a Chi2-Value of exactly .5, the for-loop in 
line 332 of Ent.java will never be broken and the array CHI_SQUARE_P 
will be accessed at the (illegal) position CHI_SQUARE_P[0][-1].

Adding a line before line 337, saying { if (i < 0) i = 0; } cures the 
problem.

Best wishes,
Karsten
