We got rid of the '../../spec_helper' style requires, but a few of them snuck
back in in recent changes.  This purges them out, replaced with the header:

    #!/usr/bin/env rspec
    require 'spec_helper'

We now use a shebang of: #!/usr/bin/env rspec

This enables the direct execution of spec tests again, which was lost earlier
during the transition to more directly using the rspec2 runtime environment.

This patch introduces managing remotely cisco IOS network devices
through ssh or telnet with a puppet type/provider.

This patch allows to manage router/switch interface
with the interface type:

interface {
	"FastEthernet 0/1":
		device_url => "ssh://user:pass@cisco2960.domain.com/",
		mode => trunk,
		encapsulation => dot1q,
		trunk_allowed_vlans => "1-99,200,253",
		description => "to back bone router"
}

It is possible with this patch to set interface:
 * mode (access or trunk)
 * native vlan (only for access mode)
 * speed (auto or a given speed)
 * duplex (auto, half or full)
 * trunk encapsulation
 * allowed trunk vlan
 * ipv4 addresses
 * ipv6 addresses
 * etherchannel membership

The interface name (at least for the cisco provider) can be any
shorthand interface name a switch or router can use.

The device url should conform to:
 * scheme: either telnet or ssh
 * user: can be absent depending on switch/router line config
 * pass: must be present
 * port: optional
 * an optional enable password can be mentioned in the url query string

Ex:
To connect to a switch with a line password and an enable password:
"telnet://:letmein@cisco29224XL.domain.com/?enable=letmeinagain"

To connect to a switch/router through ssh and a privileged user:
"ssh://brice:letmein@cisco1841L.domain.com/"

Note:
This patch only includes a Cisco IOS provider. Also terminology adopted
in the various types are mostly the ones used in Cisco devices.
This patch was tested against:
* (really old) Cisco switch 2924XL with ios 12.0(5)WC10
* Cisco router 1841 with ios 12.4(15)T8
* Cisco router 877 with ios 12.4(11)XJ4
* Cisco switch 2960G with ios 12.2(44)SE

This type needs to be started again from scratch, and I'm not
going to do so for 0.24.5.

In particular, the model for red hat and sunos need to match --
they should both use the device name as the actual name.

It mocked :exists? instead of :exist?, and my provider work
changed the method call because :exists? is going away in ruby.

This directory only existed as an organizational method,
and the code never matched it, so I'm fixing it.
