* Change host resource to use getent ahosts on Linux
In InSpec 1.31, we changed the `host` resource to use `dig` instead of `getent
hosts` for name resolution because `getent hosts` does not return all entries
(only the first v6 entry if it exists, then the first v4 entry) and we wanted to
keep the Darwin and Linux implementation as close as possible. Unfortunately,
this affected users' ability to do resolution checks for entried stored in their
/etc/hosts file.
This change goes back to using `getent` for Linux and changes to `getent ahosts`
which returns both v4 and v6 records. Additionally, the Darwin provider's dig
implementation was reordered to return v4 addresses before v6 addresses to be
consistent with how `getent ahosts` returns records.

* Fix host resolution on Darwin, use dig wherever possible
The `host` and `dig` commands do not return non-zero if a query returns NXDOMAIN
or NOERROR, but the DarwinHostProvider was expecting it when deciding whether to
fall back to IPv4 if a IPv6 query failed. Therefore, the `host` resource would
not function properly when resolving hostnames on Darwin. The logic has been
changed to use `dig` short output and query for both v6 and v4 addresses.
Additionally, the LinuxHostProvider has been modified to prefer `dig` if it's
available to keep behavior similar between Darwin and Linux whenever possible.
This has the added benefit of providing v6 and v4 resolution if possible where
`getent hosts` only returns v6 if v6 records exist.

The gem resource used to determine if a gem is installed based on the exit
status of the `gem` command, however that command will return zero
if the package was found or not. This patch checks to ensure that the
`gem list` command actually includes the gem name or is empty to
determine if the gem is in fact installed.
If the gem command returns something other than a `0` exit code, then
it'll skip the resource.

Netstat will sometimes output an IPv6 address that is not
formatted correctly; the address is either truncated or uses
or implies the `::` shorthand notation twice. This yields an
invalid IPv6 address and causes IPAddr.new to choke.
This change guards against invalid IP addresses and ensures they
do not end up in the port resource's entries list.

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.

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$/)
```
