These patches try to improve our Travis CI usage (quite a few failures the last
days). This series include Peter's "Automate coverity scan uploads via Travis"
patches (https://www.mail-archive.com/qemu-devel@nongnu.org/msg457443.html).

Patch 1 is a no-op as of today, but if eventually Shippable improve their
hardware the builds will profit of it directly.

Patch 2 allow to check how many time is spent building the codebase versus
running the tests.

Patch 4/5 speed up a bit Travis building many test objects in parallel (using
all available cores) previous to run the tests sequentially (as before) so the
tests output don't get mixed.

Patch 6 use 'travis_retry' feature to avoid aborting a job on network failure
retrying 3 times (default).

Then are Peter patches improving Coverity.

Regards,

Phil.
