Godeps, vendor: convert dependency management to trash (#3198)

Browse Source 
This commit converts the dependency management from Godeps to the vendor
folder, also switching the tool from godep to trash. Since the upstream tool
lacks a few features proposed via a few PRs, until those PRs are merged in
(if), use github.com/karalabe/trash.

You can update dependencies via trash --update.

All dependencies have been updated to their latest version.

Parts of the build system are reworked to drop old notions of Godeps and
invocation of the go vet command so that it doesn't run against the vendor
folder, as that will just blow up during vetting.

The conversion drops OpenCL (and hence GPU mining support) from ethash and our
codebase. The short reasoning is that there's noone to maintain and having
opencl libs in our deps messes up builds as go install ./... tries to build
them, failing with unsatisfied link errors for the C OpenCL deps.

golang.org/x/net/context is not vendored in. We expect it to be fetched by the
user (i.e. using go get). To keep ci.go builds reproducible the package is
"vendored" in build/_vendor.

# Vendored Dependencies
Dependencies are almost all vendored in at the standard Go `/vendor` path. This allows
people to build go-ethereum using the standard toolchain without any particular package
manager. It also plays nicely with `go get`, not requiring external code to be relied on.
The one single dependent package missing from `vendor` is `golang.org/x/net/context`. As
this is a package exposed via public library APIs, it must not be vendored as dependent
code woulnd't be able to instantiate.
To allow reproducible builds of go-ethereum nonetheless that don't need network access
during build time to fetch `golang.org/x/net/context`, a version was copied into our repo
at the very specific `/build/_vendor` path, which is added automatically by all CI build
scripts and the makefile too.
