Ensure BN_asc2bn, BN_dec2bn, and BN_hex2bn never give -0. When |BN_dec2bn| and |BN_hex2bn| were merged (way back in the initial BoringSSL change), the neg flag was set too soon and could be cleared by |BN_add_word|. This is an import of upstream's c85573cc. The unittest change isn't included here because bn_test.c has changed significantly in upstream and BoringSSL unittests aren't run in the Android environment. Bug: 20523350 Change-Id: Iaf8efe2fe3419218437f5ebb9a15f73559860a0f
