Build: make boost 1.58 minimum requirement. Fixes #956

[anonimal]

Personally, I would hold off on merging this until #951 and related documentation are resolved.

I have a feeling if #951 isn't resolved by the same time this is merged, there will be swarm of complaints about the build (e.g., any Debian stable users who don't know how to use apt-get, etc.).

Would like to confirm both libboost1.58-dev and libboost1.58-tools-dev are available in the Ubuntu universal repository. So can go ahead and make it a minimal version

Would it be much work to make it require 1.58 only for CLANG (since AFAIK it's only CLANG that requires it) ? 1.58 seems a bit new (about a year old), but if it's too annoying to make conditional, I'm fine with the patch.

@moneromooo-monero if you look at #956, you'll see that its not just about clang but rather kovri too.

[moneromooo-monero]

Yes, I know kovri requires that, but since it's separate for now, I think bumping to 1.58 represents a gratuitous denial of build since it'd work just fine (assuming the user has GCC). Again, no strong opinion about it.

Good point, but FreeBSD packages boost 1.55.0 and clang 3.4.1 by default. Is anyone actively developing BSD builds?
