Fix crypto:rc4_encrypt_with_state/2 (Gmail SSL issue)

[Paul Guyot]

Hello,

There is a simple bug in crypto:rc4_encrypt_with_state/2 NIF binding. As a result, RC4 stream cipher does not work, and one cannot connect to SSL servers that want to use an RC4 cipher suite (e.g. smtp.gmail.com).

The fix is available here, with a non-regression test:
git fetch git://github.com/pguyot/otp.git pg/fix-crypto-rc4_encrypt_with_state

Regards,

Paul
