Add config to travis to do a Coverity Scan build and upload, using
the new run-coverity-scan script.

There is an official integration between Travis and Coverity Scan:
 https://github.com/travis-ci/travis-build/blob/master/lib/travis/build/addons/coverity_scan.rb
which slurps values out of the .travis.yml and downloads a build
script from Coverity which does the bulk of the work:
 https://scan.coverity.com/scripts/travisci_build_coverity_scan.sh

However we choose to roll our own since this seems less
confusing and also allows us to include debug features
(notably the ability to do a "dry run" test which doesn't
actually upload anything).
