Commit Message

Obfuscated QUIC random stream fixes and improvements

- ObfuscatedPacketConn.WriteTo must support concurrent
  calls. Added mutex around random state calls, as
  concurrent calls to [XOR]KeyStream corrupted internal
  state.

- Replaced random stream RC4 with chacha20;
  https://en.wikipedia.org/wiki/Rc4#Biased_outputs_of_the_RC4:

  "The keystream generated by the RC4 is biased in varying
   degrees towards certain sequences making it vulnerable to
   distinguishing attacks. [...] Such bias can be detected by
   observing only 256 bytes."

- With using Yawning/chacha20 KeyStream API instead of
  XORKeyStream, don't need to initialize buffer to 0s.

- Add benchmark to verify that getPaddingLen performance is
  competitive with SecureRandomRange (getPaddingLen is 10x,
  faster as tested now).
