build: add ci.go, use it everywhere

The new build script, ci.go, replaces some of the older shell scripts.
ci.go can compile go-ethereum, run the tests, create release archives
and debian source packages.

+Debian Packaging
+----------------
+
+Tagged releases and develop branch commits are available as installable Debian packages
+for Ubuntu. Packages are built for the all Ubuntu versions which are supported by
+Canonical:
+
+- Trusty Tahr (14.04 LTS)
+- Wily Werewolf (15.10)
+- Xenial Xerus (16.04 LTS)
+
+Packages of develop branch commits have suffix -unstable and cannot be installed alongside
+the stable version. Switching between release streams requires user intervention.
+
+The packages are built and served by launchpad.net. We generate a Debian source package
+for each distribution and upload it. Their builder picks up the source package, builds it
+and installs the new version into the PPA repository. Launchpad requires a valid signature
+by a team member for source package uploads. The signing key is stored in an environment
+variable which Travis CI makes available to certain builds.
+
+We want to build go-ethereum with the most recent version of Go, irrespective of the Go
+version that is available in the main Ubuntu repository. In order to make this possible,
+our PPA depends on the ~gophers/ubuntu/archive PPA. Our source package build-depends on
+golang-1.6, which is co-installable alongside the regular golang package. PPA dependencies
+can be edited at https://launchpad.net/%7Elp-fjl/+archive/ubuntu/geth-ci-testing/+edit-dependencies
+
