vendor: update all dependencies

* Update all dependencies
  * Remove all `[[constraint]]` from Gopkg.toml
  * Add in the minimum number of `[[override]]` to build
  * Remove go get of github.com/inconshreveable/mousetrap as it is vendored
  * Update docs with new policy on constraints

+// Package sign signs small messages using public-key cryptography.
+//
+// Sign uses Ed25519 to sign messages. The length of messages is not hidden.
+// Messages should be small because:
+// 1. The whole message needs to be held in memory to be processed.
+// 2. Using large messages pressures implementations on small machines to process
+// plaintext without verifying the signature. This is very dangerous, and this API
+// discourages it, but a protocol that uses excessive message sizes might present
+// some implementations with no other choice.
+// 3. Performance may be improved by working with messages that fit into data caches.
+// Thus large amounts of data should be chunked so that each message is small.
+//
+// This package is not interoperable with the current release of NaCl
