When we are building in detached head, we cannot easily obtain the same information as we can if we're in non-detached head.
However, one thing we _can_ obtain is the git-hash and git-date. Currently, we omit to include the git-date into the build-info, which causes problem for reproducable builds which are on a detached head.
This change fixes it to include the date-info always.
This PR cleans up the CI build system and fixes a couple of issues.
- The go tool launcher code has been moved to internal/build. With the new
toolchain functions, the environment of the host Go (i.e. the one that built
ci.go) and the target Go (i.e. the toolchain downloaded by -dlgo) are isolated
more strictly. This is important to make cross compilation and -dlgo work
correctly in more cases.
- The -dlgo option now skips the download and uses the host Go if the running Go
version matches dlgoVersion exactly.
- The 'test' command now supports -dlgo, -cc and -arch. Running unit tests with
foreign GOARCH is occasionally useful. For example, it can be used to run
32-bit tests on Windows. It can also be used to run darwin/amd64 tests on
darwin/arm64 using Rosetta 2.
- The 'aar', 'xcode' and 'xgo' commands now use a slightly different method to
install external tools. They previously used `go get`, but this comes with the
annoying side effect of modifying go.mod. They now use `go install` instead,
which is the recommended way of installing tools without modifying the local
module.
- The old build warning about outdated Go version has been removed because we're
much better at keeping backwards compatibility now.

* internal/build: support building with missing git
* docker: add git history back to support commit date in version
* internal/build: use PR commits hashes for PR builds
* .dockerignore, internal/build: Read git information directly from file
This commit changes the way of retrieving git commit and branch for build
environment from running git command to reading git files directly.
This commit also adds required git files into Docker build context.
fixes: #15346
* .dockerignore: workaround for including some files in .git
This commit adds a build step to travis to auto-delete unstable archives older than
14 days (our regular release schedule) from Azure via ci.go purge.
The commit also pulls in the latest Azure storage code, also switching over from
the old import path (github.com/Azure/azure-sdk-for-go) to the new split one
(github.com/Azure/azure-storage-go).
I didn't add this initially because the command I tried was too slow.
The 'git for-each-ref ...' invocation takes 40ms on my machine. That
ought to be acceptable.
This commit tweaks the debian packaging tool:
* All build environment metadata can now be overriden on the command
line. This allows testing the CI build behaviour locally.
* -unstable packages now actually contain the binaries (oops)
* packages use Go 1.7 to build
* archiving is skipped for PR builds
