This adds support for building with the source placed anywhere and no
GOPATH set. The build script handles this by creating a temporary GOPATH
in the system temp dir (or another specified location) and mirroring the
source there before building. The resulting binaries etc still end up in
the same place as usual, meaning at least the "build", "install", "tar",
"zip", "deb", "snap", "test", "vet", "lint", "metalint" and "clean"
commands work without a GOPATH. To this end these commands internally
use fully qualified package paths like
"github.com/syncthing/syncthing/cmd/..." instead of "./cmd/..." like
before.
There is a new command "gopath" that prepares and echoes the directory
of the temporary GOPATH. This can be used to run other non-build go
commands:
export GOPATH=$(go run build.go gopath) // GOPATH is now set
go test -v -race github.com/syncthing/syncthing/cmd/...
There is a new option "-no-build-gopath" that prevents the
check-and-copy step, instead assuming the temporary GOPATH is already
created and up to date. This is a performance optimization for build
servers running multiple builds commands in sequence:
go run build.go gopath // creates a temporary GOPATH
go run build.go -no-build-gopath -goos=... tar // reuses GOPATH
go run build.go -no-build-gopath -goos=... tar // reuses GOPATH
The temporary GOPATH is placed in the system temporary directory
(os.TempDir()) unless overridden by the STTMPDIR variable. It is named
after the hash of the current directory where build.go is run. The
reason for this is that the name should be unique to a source checkout
without risk for conflict, but still persistent between runs of
build.go.

LGTM: AudriusButkevicius, imsodin
Change made by:
- running "gvt fetch" on each of the packages mentioned in
Godeps/Godeps.json
- `rm -rf Godeps`
- tweaking the build scripts to not mention Godeps
- tweaking the build scripts to test `./lib/...`, `./cmd/...` explicitly
(to avoid testing vendor)
- tweaking the build scripts to not juggle GOPATH for Godeps and instead
set GO15VENDOREXPERIMENT.
This also results in some updated packages at the same time I bet.
Building with Go 1.3 and 1.4 still *works* but won't use our vendored
dependencies - the user needs to have the actual packages in their
GOPATH then, which they'll get with a normal "go get". Building with Go
1.6+ will get our vendored dependencies by default even when not using
our build script, which is nice.
By doing this we gain some freedom in that we can pick and choose
manually what to include in vendor, as it's not based on just dependency
analysis of our own code. This is also a risk as we might pick up
dependencies we are unaware of, as the build may work locally with those
packages present in GOPATH. On the other hand the build server will
detect this as it has no packages in it's GOPATH beyond what is included
in the repo.
Recommended tool to manage dependencies is github.com/FiloSottile/gvt.
- Move the Go files into script/ instead of random places
- Rewrite check-contrib.sh into check-authors.go and check-copyright.go
- Clean up build.sh a little bit

Add systemd files to deb packate
With this change, the build system only builds one ARM variant - ARMv5.
We call the build architecture simply "arm", as this is what
runtime.GOARCH says.
