* Rewrite a bunch of the hack/ directory with modular reusable bash libraries.
* Have 'build/*' build on 'hack/*'. The stuff in build now just runs hack/* in a docker container.
* Use a docker data container to enable faster incremental builds.
* Standardize output to _output/{local,dockerized}/bin/OS/ARCH/*. This regularized placement makes cross compilation work.
* Move travis specific scripts under hack/travis
With new dockerized incremental builds, I can do a no-op `make quick-release` in ~30s. This is a significant improvement.
Currently binaries are built using Go 1.2.2, which results
in larger binaries than those produced by newer versions of
Go. The Go source archive used for the build process is not
verified against its SHA1 hash.
Update the build-image Dockerfile to use Go 1.3 to build all
binaries, as a result binaries are now 20% - 30% smaller. The
Go source archive used for building binaries is now verified
against its SHA1 hash.
