Add support for chacha20-ietf-poly1305

[cuzfrog]

Thanks. chacha20-ietf seems not working properly against service that uses chacha20-ietf-poly1305

Please do not reply with simple +1s, which spawn meaningless emails to everyone related. Thanks.

chacha20-ietf-poly1305 will be necessary

This issue can be solved as follows

# Install libsodium
sudo apt-get install libsodium-dev

# Install libbotan-2.x from source
wget https://botan.randombit.net/releases/Botan-2.3.0.tgz
tar xvf Botan-2.3.0.tgz
cd Botan-2.3.0
./configure.py
make
sudo make install
sudo ldconfig

# Install libQtShadowsocks
git clone https://github.com/shadowsocks/libQtShadowsocks.git
cd libQtShadowsocks
vim CMakeLists.txt
# Change Line 8 as "On"
mkdir build
cd build
cmake ..
make
sudo make install

# Install 
git clone https://github.com/shadowsocks/shadowsocks-qt5
cd shadowsocks-qt5
mkdir build
cd build
cmake ..
make
sudo make install

Note that when building libQtShadowsocks, please merge my PR first.

@begeekmyfriend thank you, it works, but no need to do the PR change.
I rebooted my system twice, it worked.
before that, proxy return connection closed error or no response error

@begeekmyfriend @yaochx 我安装了libsodium和libbotan,然后安装了shadowsocks-qt5 , 之后打开shadowsocks没有看到加密方式里面多了chacha20-ietf-poly1305 ,难道是还要安装libQtShadowsocks? (因为电脑山没QT,所以就没装第三个) 望指教!

[begeekmyfriend]

@Super-Tree shadowsocks-qt5调用的就是libQtShadowsocks，你要注意这个宏

[yaochx]

@Super-Tree 需要源码编译安装

I have tried the solution @begeekmyfriend provided, and it works fine, thank you.

BTW: I need to install two packages:

sudo apt install libzbar-dev libqrencode-dev

[Super-Tree]

@begeekmyfriend 我已经装了第三个包libQtShadowsocks,在cmake第四个包shadowsocks-qt5的时候,cmake报错:pkg_check_modules(QSS REQUIRED QtShadowsocks>=2.0.0) 找不到这个QtShadowsocks,可是我刚才已经安装第三个包了呀, 我要怎么设置cmakelists才能让它找到QtShadowsocks. 感觉问的问题有些低级,但是我在网上查了好多也没有解决,麻烦指点一下~

[begeekmyfriend]

@wujiangGitHub 如果你是Ubuntu的话请apt安装qtbase5-dev,qt5-default（还有一个记不清了，自己网上搜），会在/usr/lib下面生成QT相关cmake模块

@Super-Tree 你的问题也类似，用apt安装
