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_new, DSA_free - allocate and free DSA objects
=head1 SYNOPSIS
#include <openssl/dsa.h>
DSA* DSA_new(void);
void DSA_free(DSA *dsa);
=head1 DESCRIPTION
These are updates/fixes to DH/DSA/RAND docs based on the fixes to the RSA docs. There were a couple of other places (including RSA) where the docs were not quite synchronised with the API that are now fixed. One or two still remain to be fixed though ...

DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
calling DSA_new_method(NULL).

DSA_free() frees the B<DSA> structure and its components. The values are
erased before the memory is returned to the system.
free NULL cleanup Start ensuring all OpenSSL "free" routines allow NULL, and remove any if check before calling them. This gets DH_free, DSA_free, RSA_free Reviewed-by: Matt Caswell <matt@openssl.org>

If B<dsa> is NULL nothing is done.
