We fail-fast and display 'stderr' in case 'pacman' returns with 'rc != 0'.
There is no point computing 'module._diff' in such case anyway.

Previously, packages were installed one at a time in a loop. This caused
a couple of problems.
First, it was a performance issue - pacman would have to perform all of
its checks once per package. This is unnecessarily costly, especially
when you're trying to install several related packages at the same time.
Second, if a package you're trying to install depends on a virtual
package that is provided by several different packages (such as the
"libgl" package on Arch) and you aren't also installing something that
provides that virtual package at the same time, pacman will produce an
interactive prompt to allow the user to select a relevant package. This
is obviously incompatible with how ansible operates. Yes, this problem
could be avoided by installing packages in a different order, but the
order of installation shouldn't matter, and there may be situations
where it is not possible to control the order of installation.
With this refactoring, all of the above problems are avoided. The code
will now work out all of the packages that need to be installed from any
configured repositories and any packages that need to be installed from
local files, and then install all the repository packages in one go and
then all of the local file packages in one go.
It's possible to compress packages using several different compression
methods, or not compressed at all. Previously, the pacman module only
supported files compressed using xz. This update ensures that all
compression types currently supported by pacman are supported by the
ansible pacman module.
The list of supported compression methods at the time of writing can be
found here:
