[apparmor] [PATCH v3 0/5] Add basic support for Coverity builds

[Tyler Hicks]

* Changes since v2:
  - Only patches 3 and 4 have changed. See those patches for details about the
    changes.
    + They're also the only patches that are awaiting acks.

I've set up an AppArmor project on scan.coverity.com:

  https://scan.coverity.com/projects/apparmor

The project is currently set to allow anyone to view the project summary while
only pre-approved folks will be able to view the actual defects.

I believe that all AppArmor maintainers now have admin access to the project.

This patch set adds support for a top level Makefile target that generates a
coverity/apparmor-<SNAPSHOT_VERSION>-cov-int.tar.gz file which is suitable for
uploading to scan.coverity.com for analysis.

An obvious future goal would be to use this basic level of support to
automatically submit builds for analysis (possibilities are each commit, each
day, each week, etc.).
