Ubuntu 18.04 will be released on April 26, 2018. Per platform policy, that means we can drop support for 14.04 and raise our minimum requirement to 16.04.

Specifically, we can begin requiring:

• gcc >= 5.3
• clang >= 3.5 (technically, Ubuntu 16.04 ships with 3.8 by default but I doubt we can take advantage of a version newer than 3.5, given the gcc requirement)
• boost >= 1.58
• openssl >= 1.0.2

This also means we can switch the codebase to C++14.
