Created jimloco/Csocket#49 to fix build with LibreSSL.

Saw that the tarball does not include Csocket.cpp, imagine that this is included with some build script?

[DarthGandalf]

Both release tarballs and nightly tarballs include it...

GitHub tarballs don't include submodules and thus are broken and they shouldn't be used.

Sorry, meant to say the GitHub repo does not include Csocket.cpp yet the tarball does

It's submodule which you should be able to find at https://github.com/znc/znc/tree/master/third_party but all changes to it belong to where you already went.
