Implement Commit Status API

This is preliminary implementation of Commit Status API, pretty much compatible with GitHub.

1. The Commit Statuses are stored in separate table: ci_commit_status.
2. The POST inserts a new row.
3. To POST execute GitLab API `post :id/repository/commits/:sha/status`. This accepts dual authorization:
- Using authorized user
- Using ci-token to allow easy posting from CI Services
4. This adds predefined variable to GitLab CI build environment: CI_BUILD_STATUS_URL, allowing to easy post status from within build (ex. with code coverage or other metrics).
5. This adds statuses to commit's builds view.
6. The commit's status is calculated taking into account status of all builds and all posted statuses.
7. The commit statuses doesn't trigger notifications.
8. The commit status API introduces two new privileges: `read_commit_statuses` and `create_commit_status`.
9. We still miss a few tests and documentation updates for API and CI.

don't set LATEST_TAG automatically in patch update guide

As discussed in https://gitlab.com/gitlab-org/gitlab-ce/issues/2607, this removes the automatic setting of the LATEST_TAG variable in the update guide, because it could get set to rc versions.

Instead, a command was added to list all tags, with the most recent one being on the end of the list. Also a note was added to prevent users from updating to new minor/major versions because the tag list includes all tags.
