Ensure that all builders include FloppyDirectories in the StepCreateFloppy options.
Changed the way the unit-tests in common/step_create_floppy_test work to use the static test-fixtures directory instead of creating the paths dynamically.
Removed a duplicate line of documentation from parallels-pvm.html.md that occurred during rebasing.
Moved the support for recursive paths from the floppy_files keyword to the new floppy_contents keyword.
Shifted some of the code around to add better logging of what's actually being copied.
Added a couple of unit-tests for the new floppy_contents implementation.
Ensured that all files that were being added were also being included in state.FilesAdded so that the older unit-tests will work.
Prevalidates hardware resources on Linux platforms for Virtualbox and
VMware builders. This is currently only available on Linux, as enabling
for both Darwin and Windows platforms, relies on cgo bindings that would
prevent effective cross-compilation.
Packer will now fail to build and validate templates if the template is
requesting that the VM to be created would allocate more system
resources than the host system has available.
This _however_ doesn't catch parallel builds that overflow the hosts
resources, will probably still need a better error message for VM's
failing to boot in that case.
Example Outputs:
```
$ $GOPATH/bin/packer build -debug ./vmware-iso.json
Debug mode enabled. Builds will not be parallelized.
vmware-iso output will be in this color.
2 error(s) occurred:
* Unavailable Resources: RAM - Requested - 204800000MB - Available 21721MB
* Unavailable Resources: Disk - Requested - 4000000000MB - Available 76701MB
```
```
$ $GOPATH/bin/packer build -debug ./vbox-iso.json
Debug mode enabled. Builds will not be parallelized.
virtualbox-iso output will be in this color.
2 error(s) occurred:
* Unavailable Resources: RAM - Requested - 10240000MB - Available 21721MB
* Unavailable Resources: Disk - Requested - 1000000000MB - Available 76701MB

The ISO builders (parallels, qemu, virtualbox, and vmware) had too
much common code which needed to be maintained separately. This change
moves that code to a common ISO configuration.
If the access_key or secret_key were loaded from
somewhere other than the packer file then
ScrubConfig can get called to scrub "" and "".
This results in very long output:
<Filtered><<Filtered>F<Filtered>i...
Don't do that.
This patch will allow to fix the following bug much faster:
```
1 error(s) occurred:
* Unknown configuration key: output_directory
```
Related configuration:
```
"output_directory ": "build/sl_base/",
```
After the patch, the error reporting will be:
```
1 error(s) occurred:
* Unknown configuration key: "output_directory¤"
```
