Document DSA and SHA. New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)

=head1 NAME
DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects
=head1 SYNOPSIS
#include <openssl/dsa.h>
DSA_SIG *DSA_SIG_new(void);
Make DSA_SIG opaque. This adds a new accessor function DSA_SIG_get0. The customisation of DSA_SIG structure initialisation has been removed this means that the 'r' and 's' components are automatically allocated when DSA_SIG_new() is called. Update documentation.

void DSA_SIG_get0(BIGNUM **pr, BIGNUM **ps, const DSA_SIG *sig);

=head1 DESCRIPTION
DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure.
DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
values are erased before the memory is returned to the system.
Make DSA_SIG opaque. This adds a new accessor function DSA_SIG_get0. The customisation of DSA_SIG structure initialisation has been removed this means that the 'r' and 's' components are automatically allocated when DSA_SIG_new() is called. Update documentation.

DSA_SIG_get0() returns internal pointers the B<r> and B<s> values contained
in B<sig>. The values can then be examined or initialised.
Document DSA and SHA. New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)
