As raised in #1526, adding an additional example showing how
a user can use the `where` accessor to find commands matching
a pattern and write a test using the results.

On Linux, netstat may show a tcp6/udp6 protocol line but include a
v4 address. This happens with AF_INET6 sockets that can accept
both v4 and v6 traffic. The port check was not properly handling
this situation and trying to pass a v4 address to URI bracketed as
if it was a v6 address.

The following new resources have been added; however, they
presently only support FreeBSD and similar.
* `zfs_dataset`: tests if a named ZFS dataset is present
and/or has certain properties.
* `zfs_pool`: tests if a named ZFS pool is present and/or
has certain properties.
Additionally, the `mount` resource has been reworked to
include support for FreeBSD; while the existing class
was renamed to LinuxMountParser.
Unit-tests were added for all of the above.

The crontab resource parses a particular user's crontab file into
individual entries and allows the user to assert information about
each entry as needed.

This pull request adds a packages resource so that we can check for pattern matches against all the packages on a system. This initially implements only dpkg support for debian-based platforms so we can cover this use case:
```ruby
describe packages(/^xserver-xorg.*/) do
its("list") { should be_empty }
end
```
This uses FilterTable so we can supply additional queries, too.
```ruby
describe packages(/vi.+/).where { status != 'installed' } do
its('statuses') { should be_empty }
end
```
Users can specify the name as a string or a regular expression. If it is a string, we will escape it and convert it to a regular expression to use in matching against the full returned list of packages. If it is a regular expression, we take that as is and use it to filter the results.
While some package management systems such as `dpkg` can take a shell glob argument to filter their results, we eschew this and require a regular expression to match multiple package names because we will need this to work across other platforms in the future. This means that the following:
```ruby
packages("vim")
```
Will return *all* the "vim" packages on the system. The `packages` resource will take `"vim"`, turn it into `/vim/`, and greedily match anything with "vim" in the name. To match only a single package named `vim`, it needs to be an anchored regular expression.
```ruby
packages(/^vim$/)
```
