When no repositories are defined in zypper, the return code
of "zypper repos" is 6. Handle that case and don't fail
if zypper_repository has to deal with an empty repo list.

The `--noreplace` argument to `emerge` is generally coupled with
`--newuse` or `--changed-use`, and can be used instruct Portage to
rebuild a package only if necessary. Simply checking to see if the
package is already installed using `equery` is not sufficient to
determine if any changes would be made, so that step is skipped when
the `noreplace` module argument is specified. The module then falls back
to parsing the output from `emerge` to determine if anything changed. In
check mode, `emerge` is called with `--pretend`, so it produces
different output, and the parsing fails to correctly infer that a change
would be made.
This commit adds another regular expression to check when running in
check mode that matches the pretend output from `emerge`.

When running in check mode, the *portage* module always reports that no
changes were made, even if the requested packages do not exist on the
system. This is because it was erroneously expecting `emerge --pretend`
to produce the same output as `emerge` by itself would, and attempts to
parse it. This is not correct, for several reasons. Most specifically,
the string for which it is searching does not exist in the pretend
output. Additionally, `emerge --pretend` always prints the requested
packages, whether they are already installed or not; in the former case,
it shows them as reinstalls.
This commit adjusts the behavior to rely on `equery` alone when running
in check mode. If `equery` reports at least one package is not
installed, then nothing else is done: the system will definitely be
changed.

- Backport config file handling from the DNF module rewrite #527
(Current config handling does not work with dnf and leads to
tracebacks when run as an unprivileged user).
- Make a mandatory requirement on yum-utils (for /usr/bin/repoquery)
because none of the fallback code works for dnf (it's unported yum API
code).
Both of these issues will be fixed better in the dnf rewrite when it is
feature complete.
Fixes#471
The documentation for the `state` field is not very clear.
It says possible values are "installed, uninstalled" and default value is "present"
The examples below alow uses `present` and `absent`.
This patch uses "absent" and "present" instead of "installed" and "uninstalled"
Moreover, this is consistent with other packaging modules, like homebrew itself
Fix bug in ansible get_package_state and get_current_version that breaks when there are multiple versions of a package installed and there is a list of packages to install.
The previous implementation used 'zip' to match requested names to installed names which fails, because rpm outputs multiple lines per package when there are multiple versions.
Testcase: Install opensuse, install multiple kernel versions (happens by update)
Before patch: calling
zypper: state=present for name={{item}}
with_items:
- kernel-desktop
- git
leads to ansible aborting.
After the patch ansible performs as expected and makes sure both packages are present.
Also the last version number is used for further update information in this version (before if only one package name was given the oldest version number was used).
* Add support for check mode
* Use "pkgin search" to guarantee 0 or 1 result
* Edit documentation for style, new feature, etc.
* General refactoring
* Lay some groundwork for future support of "state=latest"
