1/3 Updated Makefile to allow VENDOR flag (adds -vendor to version string)

2/3 Added vendor/ dir to lock down dependent pkg versions.
The author of git.schwanenlied.me/yawning/{chacha20,newhope,kyber}.git has copied
their repos to gitlab.com/yawning/ but some imports of chacha20 from newhope still
inconsistently refer to git.schwanenlied.me/, breaking build.
Licenses for chacha20 also changed from CC0 to AGPL, which may or may not be an
issue. Until the two aforementioned issues are resolved, locking to last-good
versions is probably the best way forward for now.

To build with vendored deps, use make VENDOR=1 clean all

3/3 Moved body of CI push script into bacillus/

vendor/gopkg.in/hlandau/measurable.v1/README.md

+Measurable: The useless Go metric registration package that doesn't do anything
+===============================================================================
+
+[![GoDoc](https://godoc.org/gopkg.in/hlandau/measurable.v1?status.svg)](https://godoc.org/gopkg.in/hlandau/measurable.v1)
+
+Measurable is a Go library for managing the registration of metrics such as
+counters and gauges, no matter how that metric data is eventually consumed.
+
+The most noteworthy feature of measurable is that it doesn't do anything. It
+contains no functionality for providing metric data to any external service,
+and it contains no actual metric implementations.
+
+The purpose of measurable is to act as an [integration
+nexus](https://www.devever.net/~hl/nexuses), essentially a matchmaker between
+metric sources and metric consumers. This creates the important feature that
+your application's metrics can be expressed completely independently of *how*
+those metrics are exported.
+
+Measurable doesn't implement any metric or metric export logic because it
+strives to be a neutral intermediary, which abstracts the interface between
+metrics and metric exporters.
+
+**Import as:** `gopkg.in/hlandau/measurable.v1`
+
+Measurable
+----------
+
+A Measurable is an object that represents some metric. It is obliged only to
+implement the following interface:
+
+```go
+type Measurable interface {
+  MsName() string
+  MsType() Type
+}
+```
+
+Measurable is designed around interface upgrades. If you want to actually
+do anything with a Measurable, you must attempt to cast it to an interface
+with the methods you need. A Measurable is not obliged to implement any
+interface besides Measurable, but almost always will.
+
+Here are some common interfaces implemented by Measurables, in descending order
+of importance:
+
+  - `MsName() string` — get the Measurable name.
+  - `MsType() Type` — get the Measurable type.
+  - `MsInt64() int64` — get the Measurable as an int64.
+  - `String() string` — the standard Go `String()` interface.
+
+All Measurables should implement `MsName() string` and `MsType() Type`.
+
+Measurable-specific methods should always be prefixed by `Ms` so it is clear
+they are intended for consumption by Measurable consumers.
+
+`MsName`, `MsType` and `MsInt64` should suffice for most consumers of Counter
+and Gauge metric types.
+
+Metrics should be named in lowercase using dots to create a hierarchy and
+dashes to separate words, e.g. `someserver.http.request-count`. These metric
+names may be transmuted by consumers as necessary for some graphing systems,
+such as Prometheus (which allows only underscores).
+
+Standard Bindings
+-----------------
+
+For a package which makes it easy to register and consume measurables, see the
+[easymetric](https://github.com/hlandau/easymetric) package.
+
+Of course, nothing requires you to use the easymetric package. You are free to escew it and make your own.
