Installed packages might be outdated by the time the build
runs, so we should update them.

Turns out a build job can be stuck waiting for a macOS worker to
become available for a pretty long time: if more than 5 commits
have been pushed in the meantime, the clone will be too shallow
for the worker to find the commit it's supposed to verify, and
the build job will fail.

See https://travis-ci.org/libvirt/libvirt/jobs/277244110 for an
example of the failure described.

This reverts commit 2e975abd.

Order them more logically and make sure that stuff that doesn't
need to be modified frequently if at all, such as the notification
settings, are out of the way.

Perform other very minor tweaks as well.

Since configure automatically picks up as many optional dependencies
as possible, installing more packages allows us to improve our test
coverage.

The default distribution is apparently ignored if an explicit test
matrix is provided, so we haven't actually been testing the precise
plus gcc combo.

The openwsman header files are at fault here, but precise is entirely
unmaintained at this point so the issue will never be fixed.

Better to ignore the error and have coverage over the Hyper-V driver
than disabling it: if code that would trigger the warning will be
added to libvirt, the CentOS CI will catch it.

We don't need 50 commits for our purposes, so might as well save some
bandwidth and possibly some time by making the clone shallower.

msgmerge(1) and friends are required to build libvirt, so the
corresponding package should be installed in the Travis worker.

Keeping the list of build dependencies sorted alphabetically

The HTML pages are currently validated against an XHTML 1.0 DTD.
This makes it impossible to take advantage of features that are
introduced in HTML 5, because they'll fail validation.

There is intentionally no DTD defined for HTML 5, so there's no
alternative to XHTML 1.0 DTD that we could switch to. The only
options are to stick with XHTML 1.0 forever, or drop the DTD
validation, and we pick the latter.

Disclose the content of the 'test-suite.log' file (if available) in
case of failures inside Travis-CI. This is needed to understand what
happened and to provide hints about the proper fix (if applicable).

This travis configuration tests libvirt builds on 5 platforms that we don't
exercise in the CentOS CI system.

  - Ubuntu Trusty with GCC
  - Ubuntu Trusty with CLang
  - Ubuntu Precise with GCC
  - Ubuntu Precise with CLang
  - OS-X with CLang

NB, syntax-check fails on OS-X with errors like:

   /bin/sh: /usr/bin/grep: Argument list too long

Presumably their grep impl isn't as good as the GNU one, so this test
config skips syntax-check on OS-X for now.
