libqtshadowsocks doesn't build anymore against Botan 2.11.0

[david-geiger]

Hi,

I tried to build libqtshadowsocks on Mageia Cauldron against Botan 2.11.0 but it fails to build due to:

/home/iurt/rpmbuild/BUILD/libQtShadowsocks-2.1.0/lib/crypto/cipher.cpp: In constructor 'QSS::Cipher::Cipher(const string&, std::__cxx11::string, std::__cxx11::string, bool)':
/home/iurt/rpmbuild/BUILD/libQtShadowsocks-2.1.0/lib/crypto/cipher.cpp:94:25: error: 'get_cipher' is not a member of 'Botan'
filter = Botan::get_cipher(cipherInfo.internalName, _key, _iv,
^~~~~~~~~~

Attached full log:

build.0.20190715095032.log

Hmmm! ok! "get_cipher" was moved into "botan/filters.h" header

This patch fixes build:
