Golang base image for some reason now pulls gcc 4.9 not 4.7 and failes to find g++-4.7 target. Changing to 4.9 made Dockerimage build correctly for me again.
Merge pull request #152 from banks/master

Jessie now has gcc 4.9 not 4.7.
Added a grace interval to split_test when verifying there are no dangling
intents. This allows the test writer to finish up and also any ongoing
split to complete.

Removed useless test from gossip/addr_set_test which could occasionally
fail after selecting the 10 addresses with no overlaps in 10 tries. The
test originally was predicated on a consistent seed in random number
generator, but that's apparently no longer the case with the unittests.
It wasn't a test worth keeping, though we may want to look into our test
random number generator so that at least we are logging the random seed.

add testability through docker

added a ./deploy/wrapper.sh which routes everything to the cockroach binary
except when called when with a single parameter "test", in which case we run
make test and make testrace.

Somewhat optimized the size of the resulting Docker image and set the entry
point to the new wrapper script, allowing
  `docker run "cockroachdb/cockroach" test
to run the tests inside of the container.
setup CircleCI to test through Docker with caching

The script will look for previously generated Docker images and use those in
the build of our Cockroach image. On the first run (or after the cache has been
cleared) we do a full build and store the layers.
In effect, this gets the total build time down to about two minutes, where half
of that is due to the need to run `docker load` on our currently 1.2GB sized
container.
refactor Dockerfile into a base image and deploy

The base image resides in cockroachdb/docker_base. This allows for CircleCI to
cache only this image locally, and squash it when creating the cache without
resorting to hacky shell scripting.

Updated circle.yml to do what is described above.
