(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) 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-2663) Allow string to contain leading sign in numeric conversion

This makes it possible to use an unary +/- in a string. The sign
of the converted value abides by the unary string sign. White space is
allowed around the sign, and at the end of the string.

'+ 2' + '- 2' == 0

This is of value when dealing with original data in string form
that needs to be converted. Without this it is especially difficult to
pass a negative value around in string form.
(maint) Remove redundant code
(PUP-2691) Re-adding the missing ‘description’ property to P::MT::Metadata.

Prior to Puppet 3.6.0, users had a ‘description’ property which they
could reliably expand into their module skeleton’s ERB templates.  This
property was removed from the default set of properties in Puppet 3.6.0,
which effectively broke template expansion for users relying on it.

This change ensures that users can continue to rely on this property.
(PUP-2703) Make 'tag' be a statement function

Tag function should not require parentheses.
(PUP-1852) Deprecate the 'search' function.

This function is deprecated because support for dynamic scoping
has been removed in general and this function makes it possible
to abuse the systems ability to search multiple disjunct name-spaces.
(maint) spec: allow expectations of resources from compiled manifests

Add logic to the PuppetSpec::Compiler.apply_compiled_manifest method so that
a spec test can supply a block that processes the single resources
that comprise that catalog that was compiled before it is run in a transaction.

As a proof of concept and general helper, add a apply_with_error_checks method,
that adds an expectation to never send an :err signal to each resource. This
makes spectest debugging much easier, because without expectations,
the transaction will just finish and the only reported error will be that the
end result is not as expected. When the expectation is added to each resource,
rspec will display all resource error messages as failed expectations.
(PUP-1177) allow parsedfile providers to choose a default mode

The ParsedFile provider baseclass and its companion Util::FileType module
employ Tempfile for pre-buffering generated files. If there is no actual
file at the final desination yet, copying the tempfile will preserve its
permissions, which implies a mode of 0600.

This is not desirable for all files managed by ParsedFile providers. Therefor,
the ParsedFile provider baseclass now provides an interface to change this
default mode by overriding a method.
(maint) move the file mode tests to the files spec module

It is helpful to have a simple helper method to match desired file modes
from spec tests.
(PUP-1177) make sure ssh_known_hosts is not created with mode 0600

The default mode for files that a ParsedFile provider newly creates
is 0600. This makes no sense for the ssh_known_hosts file, because it
contains public information that adds to security for all users.
(PUP-1177) update ParsedFile provider unit tests

The constructor for the :flat filetype accepts a second argument now.
This second argument must be taken into account when stubbing specific
invocations.
(PUP-1177) restore :ram FileType compatibility

The :ram filetype, as an alternative to :flat, is often used for spectests
of ParsedFile providers. The providers normally use the :flat type, but through
mocking, are made to use :ram in test context. Since the providers often pass
both supported arguments to the :flat constructor, it must be accepted by the
constructor of the :ram type as well.
(PUP-2079) Add no-op PMT generate template format.

Prior to this commit, the mechanisms available for writing skeletons containing ERB templates
were awkward at best (and broken at worst).

This change adds a new template extension for module skeletons that has the (somewhat counter-
intuitive, when described this way) behavior of performing no alterations to the given template.
In this way, one could place a file like `foo_bar.erb.template` in their module skeleton, and
generated modules would contain a file named `foo_bar.erb` with the exact contents of the
`.template` file.

This will also close pull requests #2468 and #2688.
(PUP-1100) Create_resources syntax error message spec test

This commit adds a check for the create_resources syntax error message.
If there is a syntax error, the error given by puppet master is unclear.
This commits adds a test to check that the error message is correct and
makes sense.

This only happens when the resources are auto imported, which is why I
use a fixture directory.
(PUP-1100) Fix error message with create_resources and auto-loaded class

This commit fixes the error message displayed by PM when a syntax error
is present on an file auto-loaded by create_resources.
(PUP-2798) Remove warnings for reserved words in 3x regular.

We are issuing too many deprecation warnings for people to keep up.
The migration paths is to use the future parser/evaluator to "future
proof" manifests.

This only changes the warnings for 3x regular. And is basically a
reversal of part of PUP-1027 where these warnings were added).
(PUP-2781) Generate correct dependency expressions for new modules.

Since Puppet 3.6.0, `puppet module generate` has automatically created
a `metadata.json` file for users, with a sample dependency on
`puppetlabs-stdlib` to help demonstrate the syntax for expressing
dependencies.  Unfortunately, the generated sample used an incorrect
key name (`version_range` vs `version_requirement`), which is less
useful and was introducing other problems with (e.g.) publishing to the
Forge.

This change repairs that mistake.
(maint) Remove resources_spec.rb Facter stubs

 - Facter stubs would actually cause different types to be created
   on Windows that would break tests.
 - Instead of creating stubs that affect a number of tests, carefully
   select the uid in the one test that needs to be particular about max
   UID
