Merge remote-tracking branch 'upstream/stable'

* upstream/stable:
  (PUP-2584) Make 404 warning on agent specific and an error.
  (PUP-1894) Fix issue with loading EPP from modules

Conflicts:
	lib/puppet/configurer.rb

Resolved, merging in stable's :fail_on_404 option into the node
indirection request, and keeping master's changes to set a remote env in
the node in the likely case that locally there is no matching directory
env.
(maint) Resolve some documentation TODOs in Puppet::Type

Fix some descriptions according to the @todo tags. Some todos were just
to check if the existing documentation was correct. Those were removed
after checking.
(PUP-2182) Fix yum and zypper providers virtual_package feature.

The yum and zypper package providers were installing virtual packages even when
allow_virtual was default or set to false.

For yum, the fix is to do a "yum list" command before doing an installation whenever
allow_virtual is not true.  The list command will fail on virtual
package names.  This will prevent the package from being installed as
expected and is only performed if a version is not ensured, since
virtual packages cannot be installed by version.

For zypper, the fix is to pass the --name option to zypper if not
allowing virtual packages and a version string was not ensured.

(maint) Quote class name in init.pp template

According to the style guide:

All resource titles should be quoted. (Puppet supports unquoted resource
titles if they do not contain spaces or hyphens, but you should avoid
them in the interest of consistent look-and-feel.)

A class is a resource.
(maint) Relax error match for dynmic env puppet apply test

When testing with future parser, a slightly different error message is
returned for a missing class. This patch just loosens the regex to
accept both variants.

  (PUP-2182) Fix yum and zypper providers virtual_package feature.
(maint) Correct ssl/puppet_cert_generate_and_autosign test to do what it says it's doing.

Prior to this commit, the test was incorrectly specifying autosign=false
when attempting to test the behavior when autosign is true. This looks
like a simple copy-paste error as the test right above is exactly the
same. This commit correctly specifies the autosign value.
(PUP-2382) Create FFI typedefs for Win32 API

 - Add new file windows/api_types to contain global FFI typedefs
   that can be reused wherever we attach_function for FFI
 - Replace existing function definitions with new Win32 API style
   typedefs such as :dword, :lpcstr, :handle, etc
 - Fix some API definitions that were using incorrect FFI typedefs
   such as :ulong and :long.  In FFI, these typedefs are platform
   specific and will vary in size.  On Windows, these are fixed width.
   New Win32 typedefs of :win32_ulong and :win32_long were added
   to accommodate these in function definitions.
 - Fix replace_file by passing FFI::Pointer::NULL to match it's updated
   definition.
 - Where applicable, modify FFI::MemoryPointer.new to use the Win32
   typedef being created, so .new(:dword, 1) instead of .new(:uint, 1)
 - Prefix each attach_function with an ffi_lib for the dll it's
   actually loaded in.
 - Add missing documentation / links where helpful.

(PUP-2382) Standardize FFI module conventions

 - Extend FFI with attach_function_private, which allows adding an FFI
   definition to a module privately.  This is a bit simpler than nesting
   an 'API' module / clearer than FFI definitions inside a private.
 - Unfortunately this doesn't make class / struct definitions private
   but this shouldn't be an issue in a practical sense (and isn't a
   change to the previous behavior / design)
 - Refactored existing API definitions and settled on mirroring the
   Win32 names precisely.  In some modules, the API names had been
   ruby-ified, which led to collisions.  Using the casing of the Win32
   API calls is a sufficient hint to differentiate them from Ruby code.
 - Found missing values for TOKEN_INFORMATION_CLASS that were added to
   enum
(PUP-2382) FFI Puppet feature symlink test
(PUP-2382) Require windows/string earlier

 - To allow using windows/string as a mixin, require it earlier

(PUP-2382) Refactor Windows API FFI definitions / module conventions
(PUP-2385) Puppet::Util::Windows::File refactor

 - Use wide_string as mixin from Puppet::Util::Windows::String
(PUP-2385) FFI Puppet::Util::Windows::File

 - Convert Windows MoveFileEx to FFI
 - No longer need to require 'windows/api'
(maint) Adjust new environment tests to work with PE

The changes to these tests are in two main categories:

1) Changes to file owner and group to use beaker host references so that
correct user/group settings are obtained regardless of whether a FOSS or
PE run is being performed.  Also changes to permissions to be more
permissive for group so that the puppet system user running under
Passenger can access key files.

2) Changes to basemodulepath to ensure that the modules PE master needs
to run under its /opt site module directory are always present.

In addition a few cases had to be exempted on PE altogether, notably
tests which were testing the effect of commandline environment settings.
Since running a PE master with commandline settings would require
modifying it's rack config.ru file, these tests make little sense in
this context.
(maint) Fix problems when rspec-puppet and rspec-helper are both used

This fixes a problem that arises when there is more than one
puppet test infrasturcutre "orchestrator"; e.g. rspec-puppet and
rspec-helper. They both add calls to the TestHelper and this ends up
setting up and tearing down the puppet environment for each test.

This problem has existed for a long time, but was noticed when using the
new mark/rollback to ensure test consistency.

The fix os to add a re-entrance check for before_each and after_each to
ensure that they only do the job once even if registered to be called
a number of times.
