If a executable is defined but not found the module should fail. Addresses https://github.com/ansible/ansible/issues/5781.

Fixes #4649

All modules should be using /usr/bin/python in the shebang as ansible_python_interpreter processes this (see FAQ).
Fixing for standardization purposes.

Right now key_present() is case sensitive, only uppercase key IDs work. By using "grep -i", lowercase IDs should work too.

I guess this is left over from testing

Resolves issues with newer versions of pip not having a --use-mirrors paramater for the install command

Some brew packages are not listed with their package name, e.g. libjpeg.

Updated main description to state that the yum module will handle package groups.  Added descriptions for each example, as it is unclear to (some) users that @Name implies a group install.

Same as b2542bff.

The apt module check if a packag eis valid by loking in the cache, checking only for
full name, while it should also check that the name is not just provided.

If we do this, we risk outputting two JSON payloads, which will be
unparsable.

Revert "No longer need to reference 'version_added' in docs for these, as this was quite a while ago."

This reverts commit ff0a41d4.

is installed when it isn't.

raise errors when omitted, updated changelog with new modules.

Give the module more knowledge of the package name structure.
This makes the handling of version-less flavors (like vim--no_x11)
behave properly.

While here sprinkle debug logging that is helpful when testing the
module.

This reverts commit de2f4cf0, reversing
changes made to 2c33737b.

For some reason, on my test mandriva, urpmi --force return 0
even when it cannot install a rpm. So we have to explicitely check
if the package was properly installed with a loop

external executable, to avoid the cost of forking.
Since python-rpm is not automatically present, we still fallback
on the slower rpm fork method.

even when a package is already installed, since urpmi will
always return 0 wether it install or not.

Also solves the particular problem of installing packages that have multiple versions in the repo, but specifying the exact version would be troublesome:

$ pkg install -n dovecot
The following 2 packages will be installed:

	Installing dovecot: 1.2.17
	Reinstalling dovecot-2.2.6 (options changed)

$ pkg install -n dovecot-2.2.6
The following 1 packages will be installed:

	Reinstalling dovecot-2.2.6 (options changed)

$ pkg install -n -g dovecot-2*
The following 1 packages will be installed:

	Reinstalling dovecot-2.2.6 (options changed)

is vim. It can be installed as vim--no_x11 or vim--gtk2.
