Convert openssl code not to assume the deprecated form of BN_zero().
...
Remove certain redundant BN_zero() initialisations, because BN_CTX_get(),
BN_init(), [etc] already initialise to zero.
Correct error checking in bn_sqr.c, and be less wishy-wash about how/why
the result's 'top' value is set (note also, 'max' is always > 0 at this
point).

Put the first stage of my bignum debugging adventures into CVS. This code
...
is itself experimental, and in addition may cause execution to break on
existing openssl "bugs" that previously were harmless or at least
invisible.

Change BN_mod_sqrt() so that it verifies that the input value is
...
really the square of the return value.

Sign-related fixes (and tests).
...
BN_mod_exp_mont does not work properly yet if modulus m
is negative (we want computations to be carried out
modulo |m|).

Move 'q->neg = 0' to those places where it is needed
...
(just in cases someone uses a negative modulus)

Move reduction step from BN_mod_exp to BN_mod_exp_mont_word.
...
Fix BN_mod_exp_simple for a==0 (mod m).
Skip useless round in BN_mod_sqrt (1 is always a square, no need
to test BN_kronecker for it).

Add bn_kron.c (BN_kronecker), which I forgot in the previous commit.
...
Also add the next file in advance so that I can't forget this one :-)
