These two functions behave identically if the input is a word, which is
true if bits <= BN_BITS2. This also matches upstream's version of the
function. I'm guessing the patch was originally submitted as we have it,
perhaps because we didn't notice BN_get_word at the time, and it got
switched to the existing BN_get_word function in review.

As of 67cb49d045 and the corresponding upstream
change, BN_mod_word may fail, like BN_div_word. Handle this properly and
document in bn.h. Thanks to Brian Smith for pointing this out.

BN_copy can fail on malloc failure. The case in crypto/rsa was causing the
malloc tests in all_tests.go to infinite loop.

Ensure that, when generating small primes, the result is actually of the
requested size. Fixes OpenSSL #2701.
This change does not address the cases of generating safe primes, or
where the |add| parameter is non-NULL.
