Fixes one comment that mentioned the wrong function name. Also causes
two BN random functions to fail when the output is NULL. Previously they
would silently do nothing.

Previously we generated a number that was 8 bytes too large and used a
modular reduction, which has a (tiny, tiny) bias towards zero.
Out of an excess of caution, instead truncate the generated nonce and
try again if it's out of range.

Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
