[PATCH v5 0/6] Add Travis CI support

From: Lars Schneider <redacted>

diff to v4:
* add Junio's "test_must_fail ok=" refactor that he sent as response
  to my patch. Did I attribute this to Junio in the right way by adding
  "Signed-off-by: Junio C Hamano [off-list ref]" to the commit message?
  Please let me know how to handle these cases properly!
* fix commit message wording according to Junio's suggestion
* do not accept sigpipe failures in "git cat-file" (thanks Junio)
* reorder patches (thanks Eric)
* fix incorrect space indent (thanks Eric)
* add a trap to git-p4 tests that ensure p4d is always killed

Thanks,
Lars
