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.

This moves a few things from script/ to a new directory meta/, and makes
them real Go tests. These are the authors, copyright, metalint and gofmt
checks. That means that they can now be run by
go test -v ./meta
and optionally filtered by the usual -run thing to go test. Also -short
will cut down on the metalint stuff and exclude the authors check (which
is slow because it runs git lots of times).
Mainly this makes everything easier on things like build servers where
we can now just run tests instead of do a bunch of scripting.

Otherwise all the lines from includes will be shown in the web UI instead of
just the #include ... line. This problem was introduced in #3996.

This removes the special handling of minor versions as major when the
actual major is zero, and adds the special case that upgrades from 0.x
to 1.x are considered minor. 0.x to 2.x or 1.x to 2.x etc are still
considered major.

This solves the erratic test failures on model.TestIgnores by ensuring
that the ignore patterns are reloaded even in the face of unchanged
timestamps.

Things like the package name "syncthing" was hardcoded, which is not
awesome. With this in place we can build debs called syncthing-discosrv,
syncthing-relaysrv and syncthing-relaypoolsrv. I don't actually intend
to build and publish the relaypoolsrv, but the others can be good. Using
the "syncthing-" prefix to make the obvious "apt-cache search syncthing"
actually show them etc.

Starting stuff from init() is an antipattern, and the innerProcess
variable isn't 100% reliable. We should sort out the other uses of it as
well in due time.
Also removing the hack on innerProcess as I happened to see it and the
affected versions are now <1% users.
