commit 7f7f1714f54326c6f75f5abf42ec8fa059003f11 Merge: 7b3df73f 526dc8b2 Author: Damian Johnson atagar@torproject.org Date: Sat Jun 16 16:44:32 2018 -0700

Localize protocol attributes into a LinkProtocol class

Several constants vary depending on our link protocol version. Rather than encoding a bunch of 'x if link_protocol > y else z' conditionals centralizing this in a LinkProtocol class.

LinkPrococol.for_version() normalizes an integer *or* LinkProtocol into a LinkProtocol.

Pattern we should follow is:

* Public methods should always accept an integer.

* Any time we use or store a link protocol version it's normalized to a LinkPrococol class.
