Add experimental HTTP/TLS obfuscating as an **optional extension** of shadowsocks protocol.
More discussions can be found here: https://github.com/shadowsocks/shadowsocks-org/issues/26
As this feature is still a SIP (Shadowsocks Improvement Proposal), it's very unstable and experimental. So,
1. Don't enable it unless you know what it is.
2. Be very careful when using it in production environment.
Notes:
- Test cipher CFB support just in case (i.e. OpenWrt disabled it)
- Added some inline notes, please feel free to modify or remove them.
- Sorry for my bad English
- If you want to compile for OpenWrt, please make sure this hunk[1] not exists.
- Only tested on ARM mamba (Linksys WRT1900AC v1), it works.
